ANFIS based IMC PID Controller for Permanent Magnet DC Motor

Permanent Magnet Direct Current (PMDC) motors are widely used in industrial application and PID controllers are usually applied to improve performance characteristics of PMDC motor. There are different methods for setting up PID parameters that one of them has been called Internal Model Control (IMC) which is used. parameter to modify performance characteristics of system. Sometimes setting up IMC PID parameters are hard so in this paper, ANFIS is used to add proper values with IMC PID coefficients. The proposed controller used ANFIS based coefficient modifier because it can train easily and help system to achieve desired performance characteristics. The proposed system used the fuzzy system that is extracted from training ANFIS system with desired data to improve PMDC motor performance. In this paper IMC based controller is compared with proposed strategy and simulation results shows that proposed control system have acceptable characteristic in different situation such as no-load, applied-load, changing reference speed and it is effective methods to control system in noisy condition.
