Observer-based quantized control of nonlinear systems with input saturation

摘要: This paper deals with the problem of observer-based quantized control nonlinear systems subject to actuator saturation and bounded disturbances. The nonlinearity is assumed satisfy local Lipschitz condition appear in state equation. Attention focused on design an controller such that resulting closed-loop system convergent a minimal ellipsoid for every initial emanating from large admissible domain. constant, disturbance attenuation level, domains are obtained through convex optimization problem. A sufficient existence observers guarantees asymptotic stability error dynamical system. Finally, illustrative examples provided demonstrate effectiveness proposed approach.
