摘要
The design and implementation of a DSP microprocessor based DC motor servo driver are presented. The integral variable structure control (IVSC) approach is proposed for the outer loop of the driven system. Conditions are derived which ensure the existence of a nonideal sliding motion for the IVSC approach and also prove that the described motion in the nonideal sliding region will be close to the ideal sliding motion. Simulation and experimental results show that the proposed scheme can achieve an accurate velocity/position servo tracking result and is robust to plant parameter variations and external load disturbance.
