Design of a Variable-Structure Controller for the Missile Launcher Servo System

This paper introduces the applied technologies and control principle of a missile launcher servo system, and expounds the composition, control algorithm and software implementation of its control center--variable-structure controller. The control algorithm of the controller consists of three parts--"Bang-Bang" control algorithm, "PID" control algorithm and "FUZZY" control algorithm. The controller features high speed, high precision, etc. With the advantages of small volume, low cost,high reliability and good maintenability, the servo system has a good prospect in engineering applications.
