Multiple inverters are needed in traditional multi drive system. In order to reduce the system cost and realize fault-tolerant operation, a dual induction motor drive system fed by an indirect matrix converter (IMC) with five-leg inverter is investigated in this paper. A control strategy for the drive system, which combines vector control technology for motors and SVPWM algorithm for IMC with five-leg...
The purpose of this paper is to find an innovative, high efficiency, practical and low cost control system structure with an optimized control strategy for small-scale grid-connected wind turbine with direct-driven permanent magnet synchronous generator (PMSG). This research adopts the sensorless vector control strategy based on phase-locked loop (PLL) for PMSG control, and the grid-side inverter...
This paper proposes a method to estimate the electrical parameters of Induction Motors, The electrical parameters are obtained by solving a least squares minimization problem, the method conceived to be used estimate parameters with the vector control strategy and the M sequence disturbing on the reference voltage. And experimental results are used to demonstrate the feasibility of the propose method.
