✦ Synopsis

The purpose of this paper is to present a technique for optimal synthesis of linear control systems with pulse-width modulation. The criterion of system performance is a quadratic index, which is taken in an illustrative example to be the sum of the square8 of the error at sampling instants for the case in which the input to the system is a step junction.

The technique, which is based on the state-variable concept and on dynamic programming, leads to the determination of a computer program for calculating the optimum sequence of signals to be applied to the input of the pulse-width modulator.

Pulse-width-modulation (PWM) feedback strategies have been of limited theoretical interest in the control of nonlinear mechanical systems, such as robotic manipulators. The chattering, associated with an underlying discontinuous control policy, has traditionally been regarded as a serious drawback w
