Realization of PMSM Adjustable Speed System Based on Sliding Mode Control
The PMSM mode is a nonlinear, multi-variable system with strong coupling. The sliding mode variable structure control is advantaged by its rapid response, insensitive to the change and disturbance of the variables, simple arithmetic and easy application, which furnishes a better solution for the complicated industrial control. The PMSM adjustable speed system discussed in this paper employs TMS320F2812 as the master chip, uses the controller of sliding mode variable structure under the exponential reaching law to carry out the control, gives out the position expression and incremental expression and develops the program, which is used as the software of the adjustable speed system, as per the derived arithmetic in the form of incremental type. Finally, the MATLAB simulation and specific experiments prove such system has the advantages like rapid dynamic response, small electromagnetic torque ripple and stable which result in high robustness of the system.
