In this paper, the H∞ control method as the static acceleration feedback was put forward concerned with structural uncertainty and actuator saturation. The sufficiency and necessary condition that the controller existed was proved. By simulation, it was shown that the structure could hold the favorable stability by H∞ robust control technique.
Feedback control problems for distributed parameter systems arise in a variety of physical, chemical, biological, and mechanical systems. This paper exploits the algebraic structure of the system of ordinary differential equations that arise from spatial discretization of the partial differential equation (PDE) to analyze and design feedback controllers that are robust to bounded perturbations in...
This article focuses on dynamic output feedback and robust control of quasi linear parabolic partial differential equations (PDE) systems with time-varying uncertain variables. Especially processes that are described by dissipative PDEs are considered. The states of the process required for designing controllers are dynamically estimated from limited number of noisy process measurements employing...
This paper focuses on uncertain pendulum-like systems subjected to norm-bounded parameter uncertainty in the forward path and a vector-valued periodic nonlinearity in the feedback path, and addresses the robust gradient-like behavior analysis and synthesis problems for such systems. Sufficient conditions for robust gradient-like behavior are derived in terms of linear matrix inequalities (LMIs) and...
