Abstract

The goal of this paper is to present a new approach to the pole-placement algorithm in digital control systems by using mathematic model blocks in VisSim/OptimizePRO software package environment. A digital design example, satellite attitude control system, based on the pole-placement algorithm is given. The theoretical state feedback controller can be obtained. An alternative approach using VisSim/OptimizePRO to automatically calculate the digital state feedback controller has been verified to be a very powerful method to avoid tedious theoretical design. The digital pole-placement controller can be easily obtained without the theoretical design. The calculation of the state feedback gains becomes rather easy when the sample times of digital control systems are varied. The satisfied results are shown in this paper.
