A stepper motor is usually operated in position open-loop control for simplicity. However, order to improve the transient and steady-state performances of motor-based drive system, a high performance system designed feed encoder signal back form closed-loop such as general servo drive, high-performance speed loop controller can then be used overcome nonlinear characteristics motor, cogging forc...

In this paper, a smart drive system of the induction motor (IM) is proposed and adapted for applications in electric vehicles (EVs). Objectively, EV systems are robust over wide speed torque ranges. The independent encoder (encoderless) concerned with control (TCD) indirect rotor field-oriented (IRFOC) using sliding mode observer (SMO). This arrangement monitoring techniques smartly integrated ...

The Brushless DC Motor drive systems are used widely with renewable energy resources. power converter controlling technique increases the performance by novel techniques and algorithms. Conventional approaches mostly focused on buck converter, Fuzzy logic control various switching activity. In this proposed research work, QPSO (Quantum Particle Swarm Optimization algorithm) is state of from gen...
