Effective Speed Control in 3-Phase BLDC Motor by Reaching Law Based Sliding Mode Technique
نویسنده
چکیده
In this paper a Sliding mode controller (SMC) scheme based on the power rate reaching law approach has been proposed for the inner loop current control of the 3-Phase Brushless DC motor (BLDC) drive. A proportionalintegral (PI) controller is used to control the outer loop speed performance. The developed PI-SMC control scheme is simulated on MATLAB/SIMULINK platform under a sequence of load torque disturbances incremented up to 100% to demonstrate efficient speed tracking. Experimental verification of the developed scheme is carried out under no load conditions using National Instruments Data Acquisition Card (NI DAQ) card 6229 as the interface with MATLAB environment. The experimental results validate the performance of the developed scheme. General Terms Sliding Mode Control
