Abstract :
The exploitation of wavelet theory in a control structure of a Brushless DC (BLDC) motor integrated in a Fuel Cell Electric Vehicle is proposed. The controlling structure, consisted of two interrelated multiresolution PID (MRPID) controllers, regulates: a) BLDC motor torque through DC current and b) rotor speed. The proposed structure is deployed on an algorithm that exploits inherit wavelet filtering capabilities for improving control dynamics and stability over a wide operational range. Full system (FCEV) performance is assessed for both cases of MRPID and conventional PID controlling structures via simulation in MATLAB/Simulink environment.
