Design of Servomechanism for Nonlinear Digital Systems

Abstract

In this paper, the servomechanism synthesis for nonlinear digital systems is considered. Nonlinear characteristics are often found in modeling systems. Nonlinear digital systems with input-channel nonlinearity are treated. Firstly, we present feedback laws that ensure the stability of compensated nonlinear digital systems. Next, using these results, we derive sufficient conditions in order for the controlled systems to satisfy the desired servomechanism performance.
