摘要:Direct torque control (DTC) has been employed to give fast torque response, which is very
important in traction and electric vehicle applications, in high dynamic performance Induction
Motor (IM) drives. Fast torque response can be achieved by optimizing the selection of the
inverter voltage vectors in the conventional DTC. This paper introduces a method for selecting
voltage vectors; in DTC controlled IM drives, to achieve fast torque response at constant
switching frequency. Also, the application of the Fuzzy PID (FPID) control technique improves
the system speed and torque responses. Simulation results show that both torque and speed
responses are faster with the proposed controller than the conventional DTC.
