Design of PAM and PWM controllers for sampled-data interval systems
Abstract
In this paper, we address two issues: digital redesign of a continuous-time interval system using an interval chebyshev quadrature approximation method; and translation of the newly digitally redesigned pulse-amplitude modulated controller into an equivalent pulse-width modulated controller via a high-order Taylor-series approximation method. Using this new interval digital redesign technique, the dynamic states of the digitally controlled sampled-data interval system are able to closely match those of the original analogously controlled continuous-time uncertain system for a relatively longer sampling period.
