摘要

In a networked control system (NCS) environment, where all closed-loop signals (control and state) are quantized, we consider the problem of establishing prescribed, transient, and steady-state, performance guarantees on the output tracking error (minimum convergence rate, maximum steady-state error). The controlled system is of high relative degree, multi-input multi-output (MIMO), uncertain, nonlinear, and time-varying. The proposed control solution is of low-complexity, in the sense that no hard calculations, analytic or numerical, are involved. Illustrative simulations clarify and verify the developed control scheme.
