The Computer-controlled Dual Closed Loop Dc Sr System

With the rapid development of computer technology, it is widely used in the control field. This paper researches DC-drive speed system with a dual-converter and dual-closed-loop based DSP, discussing a new control method that combines DSP with DC-drive. Based on the overall review of control object, the emphasis is put on the part of control system, which includes the discussion of hardware selection and software environment, control policy and algorithm, etc. It has a simulation on classic DC-drive speed control system with MATLAB so as to get reasonable parameters. It fully utilizes the advantage of DSP that are abundant interface and fast speed. By comparing the different schemes, it chooses DSP and other peripheral devices that can satisfy the system requirement and application software is realized.
