Fuzzy Pid2 Speed Controller For Permanent Magnet Synchronous Motors (Pmsm)

There have been many studies on the application of PMSM control methods; however, the motor has complicated non-linear characteristics so that it is difficult to control it, especially when there are changes in parameters of the motor. Intelligent control techniques such as fuzzy logic have been developed and applied to improving the quality of motors speed control. There are many comparative studies between fuzzy logic and classical PI controller and all of these studies come to a conclusion that it is better to use fuzzy logic controller. However, the changes in motor parameter is difficult in control process and control quality. In this paper, writers propose a method of using PID2 fuzzy logic control. This is the PID fuzzy self control but having PID exponential control. With the application of the exponent speed of parameter control to controlling the speed of PMSM, as a result, the control quality is good and the reliability is high
