Development of fuzzy controlled chopper drive for permanent magnet DC motor

摘要

In this article the fuzzy logic based closed loop chopper controlled permanent magnet DC motor drive is proposed for orthopedic surgical simulators. The proposed drive consists of an inner current control loop and an outer speed control loop. The fuzzy technique is used in the speed loop and the system is simulated using Matlab/Simulink. The steady state and transient state responses of the proposed fuzzy system are compared with conventional PI controlled system. The comparative analysis infers that the fuzzy system provides better performance.
