The Design and Realization on AC Servo Controlling System

　　The Design and Realization on AC Servo Controlling System
　　Servo technology have rapidly changed from DC Servo system to AC servo system,AC Drive have become main mode in drive field,research high performance AC servo system have important realistic meaning.The mathematical models of AC PMSM is founded at first,analyzing rotor magnetic field-oriented vector control theory and method, then the Cast Alnico Magnet simulation research based on MATLAB/SIMULINK is completed, validates the feasibility of control theory and provides the theory basis for the realization and debugging of real system.Aiming at the digital controller using TMS320LF2407A as control chip, particularly introduce how to realize SVPWM signal. This method have advantages ,for example ,a clear physics idea﹑simple arithmetic﹑high efficiency of DC voltage﹑easily realized numeric.At last, the paper introuduces the system design and realize according to the request of hardware and software.In terms of the hardware, analyzing and designing the system main circuit﹑communication circuit﹑signal manage circuit;In terms of the software, real time control program which adopts the modularization idea is compiled based on C http://www.chinamagnets.biz/Alnico/Cast-Alnico-Magnet.php and assemble language.At the base of analysis and design,the paper develops a AC servo controlling hardware platform, realizes the corresponding interface and signal manage sircuit,and performs system debugging and adjust parameter,the experiment results realizes PMSM controllable running.
