A new combined speed and current control algorithm is proposed for four-switch three-phase brushless dc (BLDC) motor drives. A single-current-sensor control strategy is proposed, in which only phase-c current is being measured. Phase-c current is maintained at nearly zero level first, and phase-a and phase-b currents are regulated by speed circle. To improve the controller performance, a single-neuron adaptive proportional–integral (PI) algorithm is adopted to realize the speed regulator. Simulation and results, the proposed strategy shows good self-adapted track ability with low current ripple and strong robustness to the given speed reference model.
