Abstract

The invention relates to a position and speed simultaneous control PMSM (Permanent Magnet Synchronous Motor) simulation method which is characterized in that speed control and position control are simultaneously added into a PMSM simulation model through a multiplying unit. According to the method provided by the invention, the speed control and the position control are simultaneously added into the PMSM simulation model by adopting a multiplying unit on the basis of simulink and the traditional three-loop control model, and simulation of controlling the position and the speed of a PMSM servo system can be achieved. Optimized debugging to various parameters can be performed so as to improve the entire performance of the system.

Description

technical field [0001] The invention relates to a PMSM motor simulation method for simultaneously controlling position and speed. Background technique [0002] The servo system with AC permanent magnet synchronous servo motor (PMSM) as the driving element is the intermediate link between the numerical control device and the mechanical structure. The performance of the servo system is the main factor determining the accuracy and productivity of the entire numerical control system. The motion servo is generally a three-loop control system, which is the current loop, the speed loop, and the position loop from the inside to the outside. Designers often use computer simulation and experimental verification methods to debug various performance parameters. The current simulation method is based on classical control theory, and the research object of classical control theory is a single-input, single-output automatic control system. Therefore, it is impossible to control the speed ...
