Developing & Research On A Servo Electromotor Controller Software System Based On SCM

Along with the development of numerical control technique,it is so convenient to control motion in system of robot and numerical control machine for all kind of motion controllers appeared. And that the biggest factor to affect the system performance in numerical control system is the controller system of servo. And the price of those controller systems is too expensive in the current market. So developing a kind of low-priced, current opening and real time motion controller software system is great development of midtype and minitype numerical control system.DSP is the new digital processor, have the running rate quick and memory space big, is easy to satisfy the servo system the request, but develops the production cost is high, the development cycle is long. But MCS is most typical and popular inserts system. It is integration and so on CPU, RAM, ROM, I/O connection as well as interruption system to with together the silicon chip component Because its volume is small, the function is strong, the reliability is good, the price is inexpensive, the power loss is small, the instruction is simple, is easy and the development, simultaneously because inserts the type C language the promoted popularization, thus prepares user's welcome. The MCS takes one kind of mature control chip, suits the chip of the axis number not many servo-controls system.This paper developed one set the motion controller software system. Hardware framework of the system is based on MCS, including 12_bit multiplying D/A conversion , time interrupt pulse receiving, zero check,out-in, on-off and warning circuit. Software of the system composed of upper software and down software, is joined via serial port. Upper software finish user's interface faction, including user's procedure editors mainly, user's procedure manages, status display etc; Down software finish control faction of electromotor movement, mainly including the servo procedure, the decipher procedure of user's procedure, dealing with procedure, and in operation trouble of the electromotor etc .And PID controller is designed, PID control arithmetic is programmed, parameters of control system are adjusted online, experiment is researchedand the result is analyzed. Experimental result showed this software system reliability highly and simple, fitting require of design, can meet the require of certain precision position control of servo electromotor.
