The new BMI based method for robust stabilizing PID controller design for linear uncertain system is proposed. The general constrained structure of controller matrix is considered which is appropriate both for output feedback and decentralized control. The developed control design scheme aims at robust stabilization with guaranteed cost. The extended quadratic performance index is used including the...
This paper presents an output feedback sliding mode control algorithm for linear MIMO systems with mismatched parameter uncertainties along with disturbances and matched nonlinear perturbations. A scheme of the output-dependent integral sliding surface is proposed and a control law is then designed to satisfy the reaching and sliding condition. Through utilizing Hinfin control analytical technique,...
This paper investigates the problem of robust guaranteed control for sampled-data systems with time-varying norm-bounded parametric uncertainties in the state matrix and input matrix. Attention is focused on the design of a causal dynamic output feedback sampled-data controller which guarantees the asymptotical stability of the closed-loop system and the quadratic performance index less than a certain...
We consider a tracking problem for a partially feedback linearizable nonlinear system with stable zero dynamics. The system is uncertain and only the output is measured. We use an extended high-gain observer of dimension n+1, where n is the relative degree. The observer estimates n derivatives of the tracking error, of which the first (n-1) derivatives are states of the plant in the normal form and...
