Abstract
The goal of this chapter is to implement the quadratic optimal control algorithm in PC-USB-Based real-time control systems by using mathematic model blocks in VisSim/USB software package environment and a USB-based module. PC is used as a controller to apply quadratic optimal control algorithm in PC-USB-Based real-time control systems. First, a design example based on the quadratic optimal control algorithm is given. The theoretical state feedback controller can be obtained. An alternative approach using VisSim’s OptimizePro to automatically calculate optimal state feedback controller has been verified to be a very powerful method to avoid tedious theoretical design. Second, the model of the real control system, FB-33 control system, can be set up in VisSim. The quadratic optimal controller can be easily obtained without the theoretical design. Finally, the VisSim/USB is used to implement the quadratic optimal control and USB-Based module to control the FB-33 servo control system. The satisfied results are shown in this chapter.
