Controller design of missile actuator using DSP

This paper proposes a design method of the position, velocity, and current controller for a hall sensored BLDC motor using TMS320F2812, a velocity estimation algorithm using a hall sensor, and a robust controller design method for an actuator system with uncertainties. The actuator for missiles requires high precision, fast response, and smaller size. The controller of the actuator should also satisfy these requirements. Although the analog controller provide precise control and fast response, the implementation of control algorithm and the modification of controller design are not easy. However, the digital controller solves these difficulties of the analog controller, since it implement the control algorithm as software. Moreover, it is easy to simulate under MATLAB/SIMULINK with the digital controller, which makes the digital controller more preferred.
