This paper proposes a combined control strategy for direct matrix converters (DMC) to stabilize the input side filter without any passive damping, simultaneously realizing the field oriented control (FOC) of an induction machine (IM) at the output. The speed control of the FOC with subsidiary torque control is left untouched. The rotor flux control loop is extended to a cascaded structure that additionally...
The knowledge of electrical and mechanical parameters of high-performance electromechanical drive systems is of paramount importance for designing high-performance controllers and/or developing accurate simulation models. By high-performance control is meant least torque (position) ripple for torque (position) control. Machine parameters are typically load and temperature dependent. This makes their...
This paper proposes a simple technique to get maximum power of wind energy conversion system (WECS) without using sensors for wind and rotor speed of the permanent magnet synchronous generator (PMSG). It uses the measurements of DC current and DC voltage to obtain maximum power point tracking (MPPT) by controlling the duty cycle of the DC-DC boost converter switch. Moreover, a PI control is employed...
