For disadvantages of the large flux and torque ripple and current waveform distortion of Direct Torque Control (BASIC-DTC), the DTC scheme for induction motor based on torque angle closed-loop control was presented and the proposed scheme was realized with three methods of torque angle closed-loop control. The main characteristics of three methods of torque angle closed-loop control for the proposed scheme was analyzed, emphasizing their advantages and disadvantages. The performance of three methods of torque angle closed-loop control for the proposed scheme was studied in terms of flux and torque ripple, current waveform distortion and transient responses. Simulation results showed that the proposed scheme improves the performance of induction motor BASIC-DTC by combining low flux ripple, low torque ripple and low current waveform distortion’s characteristics with fast dynamics.

Combining with some fuzzy of the direct torque control and the fuzzy control which is often used in the traditional AC motor control,we put forward a direct torque control theory based on the fuzzy rule. The brushless doubly-fed machine(BDFM) closed-loop control system with the direct torque control based on the fuzzy rule is simulated by using of the Matlab/Simulink software, and the simulation results show that the closed-loop control method is correct and effective.

There are two classic strategy for AC motor control, they are vector control and direct torque control. In this paper, a new closed-loop control method based on vector control is proposed. We first introduce the basic formula of the J-M transform strategy. Secondly, the control block diagram of closed loop control based on J-M transform is analyzed in detail. Finally, the results of simulation are carried out. The simulation results show that the method of closed loop control based on J-M transform strategy can control AC motor effectively.

Torque ripple reduction is one of the major challenges in switching table-based direct torque control (DTC) while operating for open phase faults of an induction motor, as the switching vectors are unevenly distributed. This can be minimized by increasing the level of the inverter and with the use of multi-phase motors. Fuzzy logic-based DTC is another solution to the above problem. In this paper, a comparative analysis is done between switching table-based DTC (ST-DTC) and fuzzy logic-based DTC for increasing the performance during open phase faults of a five-phase induction motor. The result shows that in fuzzy logic-based DTC with a two-level inverter, the torque ripple is reduced by 5.164% as compared with ST-DTC with a three-level inverter. The fuzzy logic-based DTC with the three-level inverter also gives better performance as compared with fuzzy logic-based DTC with the two-level inverter. The current ripple also reduced by 9.605% with respect to ST-DTC. Thus, fuzzy logic-based DTC is more suitable and cost effective for open phase fault-tolerant drives.

The asynchronous or Induction Motor (IM) is one of the most widely used electrical machines in the world, due to the three following advantages namely 1.Their construction is simple and rugged 2.The absence of slip rings, commutators and brushes make it cheaper, and 3.It is also maintenance free compared to DC motors and Synchronous motor due to wear and tear of brushes, slip rings and commutators respectively. The Section 1 deals with the introduction of induction motor and Direct Torque Control scheme. Section 2 briefly discusses the types of Induction motor. Section 3 tells about the control strategies of Induction motor respectively scalar control and vector control, and also briefly explains about Direct Torque Control (DTC) method. The Section 4 discuss about the Types of Control Strategies for Torque ripple Reductions in DTC as well as the two proposed schemes namely 1.Fuzzy Logic Controller (FLC) for DTC-SVM and 2.Artificial Neural Network (ANN) controller for DTC-SVM respectively for IM and its results, The two proposed schemes uses Hybrid Asymmetric Space Vector Pulse Width Modulation (HASVPWM) for switching the inverter. The Section 5 revels about the modern advanced techniques such as ANN and FLC based DTC.
