This paper presents a high performance Direct Torque Control (DTC) theme for the induction motor using Indirect Matrix Converter (IMC). To improve the dynamic behavior of motor, Active Learning Method (ALM) is implemented on the DTC. The ALM uses its own modeling technique called the ink drop spread (IDS) method. Functionally the IMC is very similar to the Direct Matrix Converter (DMC) but it has separate line and load bridges. In the inverter stage, the classical DTC method is employed. In the rectifier stage, in order to reduce losses caused by snubber circuit the rectifier four–step commutation method is employed. By suitably selecting switching pattern and using Active Learning Method the electromagnetic torque ripple of the motor is effectively reduced. The simulation results of proposed strategy and confirm its effectiveness and accuracy.<\div>
