2014 Improved set-points tracking of remotely operated underwater vehicles through a supervised pid control scheme
JOURNAL OF MARINE ENGINEERING AND TECHNOLOGY
Autore/i: Ippoliti, Gianluca; Jetto, Leopoldo; Longhi, Sauro
Classificazione: 1 Contributo su Rivista
Abstract: This paper considers the position control problem of an underwater vehicle used in the exploitation of combustible gas deposits at great water depths. The use of a single, time invariant PID controller may result in an unsatisfactory set-point tracking. To cope with this problem, a globally non-linear regulator given by the connection of a supervisor with a finite family of properly chosen PID controllers is here proposed. Each PID is designed to obtain a specific desired feature of the step response and the supervisor governs the switching among them to obtain an overall time-varying control law yielding a globally satisfactory output behaviour. The switching logic is driven by the numerical values assumed by some suitably defined cost functionals of output prediction errors. The performance of the switched controller so obtained is evaluated by numerical simulations.

2009 LMI conditions for the stability of linear uncertain polynomially time-varying systems
IEEE TRANSACTIONS ON AUTOMATIC CONTROL
Autore/i: Ietto, Leopoldo; Orsini, Valentina
Classificazione: 1 Contributo su Rivista
Abstract: This technical note investigates the robust stability of uncertain linear time-varying systems with a mode-switch dynamics. Each mode is characterized by a dynamical matrix containing elements whose time behavior over bounded time intervals is described by interval polynomials of arbitrary degree. Using a quadratic Lyapunov function polynomially depending on time, stability conditions for each mode are stated in terms of linear matrix inequalities (LMIs). The stability conditions of the switching system are stated both in terms of minimum and average dwell time. A salient feature of the technical note is that the single-mode stability conditions given here allow the parameters and their derivatives to take values over arbitrarily large uncertainty sets.

2009 Relaxed conditions for the exponential stability of a class of linear time-varying systems
IEEE TRANSACTIONS ON AUTOMATIC CONTROL
Autore/i: Ietto, Leopoldo; Orsini, Valentina
Classificazione: 1 Contributo su Rivista
Abstract: This paper states new sufficient conditions for the exponential stability of linear time-varying (LTV) systems of the form $dot x(cdot) = A(t) x(t)$. The approach proposed derives and uses the notion of perturbed frozen time (PFT) form that can be associated to any LTV system. Exploiting the Bellman-Gronwall lemma, relaxed stability conditions are then stated in terms of "average" parameter variations. Salient features of the approach are: pointwise stability of $A(cdot)$ is not required, $|dot A(cdot)|$ may not be bounded, the stability conditions also apply to uncertain systems. The approach is illustrated by numerical examples.

Classificazione: 2 Contributo in Volume
Abstract: Underwater vehicles operate in dynamical environments where sudden changes of the working conditions occur from time to time. The need for an effective control action calls for refined techniques with a high degree of robustness with respect to large parametric variations and/or uncertainties. Supervised switching control gives the theoretical framework where appropriate control strategies can be developed. Both the switching algorithms proposed here are based on a multiple models approach to describe the different operating conditions.

2005 Localization of mobile robots: Development and comparative evaluation of algorithms based on odometric and inertial sensors
JOURNAL OF ROBOTIC SYSTEMS
Autore/i: Ippoliti, Gianluca; Ietto, Leopoldo; Longhi, Sauro
Classificazione: 1 Contributo su Rivista
Abstract: An autonomous mobile robot must be able to elaborate the measures provided by the sensor equipment to localize itself with respect to a coordinate system. The precision of the location estimate depends on the sensor accuracy and on the reliability of the measure processing algorithm. The purpose of this article is to propose a low cost positioning system using internal sensors like odometers and optical fiber gyroscopes. Three simple localization algorithms based on different sensor data processing procedures are presented. Two of them operate in a deterministic framework, the third operates in a stochastic framework where the uncertainty is induced by sensing and unmodeled robot dynamics. The performance of the proposed localization algorithms are tested through a wide set of laboratory experiments and compared in terms of localization accuracy and computational cost.

Abstract: In general, interval plants with a large uncertainty can not be robustly stabilized by a linear, time-invariant controller. The solution presented in this paper is in terms of an overall non linear control law given by the connection of a linear, deterministic, time-varying compensator and of a supervisor. The compensator may assume a finite number of possible different configurations, at least one of the which stabilizes the plant. The task of the supervisor is that of determining the switching instants of a scanning among the elements of the family, according to a suitably defined experimental test on the output of the system

Classificazione: 2 Contributo in Volume
Abstract: A basic requirement for an autonomous mobile robot is to localize itself with repect to a given coordinate system. In this regard two different operating conditions exist: structured and unstructured environment. The relative method and algorithms are strongly influenced by the a priori knowledge on the environment where the robot operates. If the environment is known, a proper multisensor system endowed with an efficient data fusion algorithm may provide a very accurate localization. In this chapter the localization problem is formulated in a stochastic setting and a Kalman filtering approach is proposed for the integration of odometric, gyrocope, sonar and video camera measures. If the environment is only partially known the localization algorithm need preliminary definition of suitable environment map. Different probabilistic methods for sensory data fusion aimed at increasing the environment knowledge are proposed and discussed.

2004 Adaptively Switched Set-point Tracking PID Controllers
In Proceedings of the 12th Mediterranean Conference on Control and Automation
Autore/i: Ippoliti G.; Jetto L.; Longhi S.; Orsini V.
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: This paper investigates the problem of improving the output step response obtainable with PID controllers. The solution proposed is based on a supervisory switching control. First, a family of candidate stabilizing conventional PID regulators are designed on the basis of a suitable plant model. For each controller the corresponding feedback connection with a plant model is defined and the resultant output prediction error is used to form a real, positive definite functional giving a measure of the future controller performance. At any time instant, the supervisor exploits these measures for on-line selecting the most appropriate controller to be connected to the plant at the same time instant. The stability of the control system is guaranteed by the introduction of a suitably defined dwell time into the switching logic.

Abstract: This paper provides a parameterization of all output feedback periodic controllers providing closed loop invariant polynomials varying over some assigned polytopes for linear discrete-time periodic plants. Using the notion of time invariant system associated to a periodic system the parameterization is provided in terms of the general solution of a suitably defined matrix diophantine equation.
