Fault-Tolerant Stabilization in Discrete-Time Multiple-Integrator Networks with General Information Sharing

The paper considers a network of agentswith identical discrete-timemultiple-integrator dynamics. The agents share information according to an arbitrary topology. The information is relative to the states corresponding to some of the highest integration levels.With reference to this setting, a decentralized stabilization problem is faced, under the further assumption that faults may occur in the communication apparatus of one or several of the agents. A necessary and sufficient solvability condition is presented for the problem, together with formulas for a class of least-order regulators

KONTROLA PRISTUPA PARKIRALIŠTA „DELTA“ U RIJECI

S porastom ljudske populacije i modernim načinom života, nastaje sve veća potreba za korištenjem osobnih automobila, a time i razvojem modernih parkirališnih rješenja. Pametna se parkirališta najčešće razvijaju unutar pametnih gradova, a često su upravo ona inicijatori razvoja ostalih segmenata pametnog grada. Rijeka je jedan od najvećih hrvatskih gradova s iznimnom pomorskim, turističkim i kulturološkim značajem, a parkiralište „Delta“ je kapacitetom najveće parkiralište koje sadrži moderna parkirališna rješenja sustava naplate i korištenja pretplatničkih kartica te sustav automatskog prepoznavanja registarskih oznaka (ANPR), sustav automatskog prepoznavanja vozila i autonomne motorizirane barijere. Budućnost parkirališta „Delta“ je razvoj prema sustavu usmjeravanja vozila na parkirna mjesta u kontekstu razvoja Rijeke kao pametnog grada

Robust switched control based on strictly positive real systems and variable structure control techniques

This paper is concerned with the design of variable structure controllers for uncertain switched linear plants. The proposed method is based on Lyapunov–Metzler inequalities and on properties of strictly positive real (SPR) systems, with the advantage that it can be applied in control of uncertain switched linear system. The first contribution shows that there exists a solution of the SPR synthesis for a class of linear uncertain switched systems using switched static output feedback, if and only if there exists a solution of this SPR synthesis with switched static state feedback. This result is a generalization of known conditions regarding this problem, for linear time-invariant and known (without uncertainties) plants, and offers a possible procedure for output feedback SPR synthesis: first solve the state feedback SPR synthesis and then, using the obtained solution, find a solution for the output feedback SPR synthesis. Next are presented necessary and sufficient (sufficient) conditions for the SPR synthesis for a class of linear uncertain switched systems using switched static output feedback, for plants with the same number of inputs and outputs (with the number of outputs greater than the number of inputs). Two examples illustrate the effectiveness of the robust control system, including applications of the proposed methods, considering switched static state feedback and switched static output feedback, in the design of switching control strategies for active suspensions systems in road vehicles. Performance indices such as decay rate, guaranteed cost, and restriction in the norm of controller gains are considered in these designs.
