Introduction was made to the structural characteristics and operating principle of a kind of linear and rotary permanent magnet actuator (LRPMA), whose mathematical model was analyzed. In allusion to the function characteristics of linear, rotary and helical motion which the LRPMA needed to realize, this paper designed the servo control system with the double digital signal processor (DSP) based on DSP2812 and dual-port random-access memory (RAM). This control system shared the memory to achieve real-time communication be-tween the two DSPs, and gave the design of system software and hardware, and different forms of motion control strategy. The experimental results show that the servo control system satisifes the demand of controlling.
