Torque-, speed- and position control is applied using hysteresis band control, pwm control, and variable dc- link voltage control.
7 z4 ^1 ~0 C/ i( k0 H4 pThe different control strategies are tested on the bldc motor and their peRFor-mance evaluated. The frequency content of the dc link current is investigated for each control method and the impact of commutation delay and switch-ing losses is discussed. Simulations show that all the control strategies work quite well although each method has its drawbacks. The frequency spectrum of the dc-link current shows that hysteresis band control may not be suitable where load variations are large. The variable dc-link voltage method turns out to be the best solution in applications where torque ripples and switching losses must me minimized. Commutation delay is necessary in practice, but
