N2 - The two degrees of freedom stable platform is driven by DC servo motor. The present work introduced the sliding mode variable structure control (SMVSC) into DC motor speed and angle position control system, aiming to improve the dynamic performance of DC motor, increase the precision of control when the system runs at a low speed as well as lower the high-frequency noise caused by torque ripple. Based on the mathematics model of DC motor, quadratic optimal control based switching function and exponential approach law based SMVSC controller have been designed, respectively. Simulation has been conducted with Matlab software so as to obtain a favorable speed and angle position tracking effect, minimize its responding and adjusting time as well as effectively weaken the chattering and disturbance.
