Besides, a new design of fuzzy direct torque control system of induction motor was introduced in this paper, which based on strategy of modulating the duty cycle to decrease the torque and stator flux ripple. This design uses fuzzy control block to instead of the traditional space voltage vector selector to control the inverter switch which can improve the static and dynamic performances of AC asynchronous motors, which make the whole control system have strong robustness.

Description: modified direct torque control (DTC) scheme for
interior permanent magnet synchronous machine (IPMSM) is investigated
in this paper, which features in very low flux and torque
ripple and almost fixed switching frequency. It is based on the compensation
of the error flux linkage vector by means of space vector
modulation. Modeling and experimental results show that the flux
and torque ripples are greatly reduced when compared with those
of the basic DTC.With the new scheme, very short sampling time is
not essential. All the advantages of the basic DTC are still retained.
In addition, fixed switching frequency at different operating conditions
becomes possible.

-With the beginning of the AC induction motor speed control field dominance, speed control system for high-performance induction motor research has been widespread concern. Especially in the 1980s, Direct Torque Control (DTC) appeared, with its simple and efficient way to control and further improve the performance of asynchronous motor. However, the existence of traditional DTC will produce torque and torque ripple flux hysteresis width when making steady. Therefore, high-performance control requires a narrower hysteresis width, corresponding demanding inverter switching frequency. Where high power must be low switching losses and good torque control performance is difficult to meet the needs of traditional DTC.
