Summary:
In this paper, we study the constraint control of uncertain nonlinear systems. We propose a generalization of static relatively optimal control (ROC) methods so that it is applicable to nonlinear servo systems. ROC methods use a piecewise linear feedback for linear systems to achieve a deadbeat control. To utilize the idea of ROC, we assume that nonlinear systems as incrementally poly topic uncertain systems, and consider the convergence to a region such that the error between the output and the constant reference command is less than or equal to a% of the constant reference command.
