This paper pertains to the design of a dynamic output-feedback controller for linear systems subject to both actuator and sensor quantization. The quantization errors affecting the measured output and the control input are embedded into compact sector through appropriate sector conditions. Then, the global asymptotic stabilization problem of an ellipsoidal set containing the origin is tackled. To...
The stabilization of linear uncertain time-delay systems subject to position and rate limited actuators is addressed. A saturating control law and a region, in which the stability of the closed-loop saturated system is ensured, are derived from an ARE-approach. The uncertainty is of the norm-bounded time-varying type. A local approach is chosen in the sense that no open-loop stability assumption is...
This paper addresses the problem of anti-windup design for linear systems subject to both actuator magnitude/rate saturation and to sensor saturation. Anti-windup design procedures are developed, using both measured and estimated variables, which allow the region of stability of the closed-loop system to be enlarged. The results are derived by modelling the saturated system as a linear system with...
In this paper, some tools for the analysis of a class of hybrid control systems for a continuous-time plant with input magnitude saturation are presented. We show that certain continuous-time LMI-based techniques can be extended to this setting when a dwell-time property is satisfied by the hybrid loop. Moreover, for the case in which the hybrid controller has the same order as the plant, the synthesis...
This paper addresses the problem of static anti-windup strategy for linear unstable control systems with saturated dynamics describing some aircraft flight control. The approach is based on the use of quadratic Lyapunov functions, S-procedure and a sector nonlinearity description for modelling the behavior of the closed-loop nonlinear system. Anti-windup design is investigated to increase both a domain...
