This paper presents a field programmable gate array (FPGA) implementation of a direct sliding mode current control of a synchronous machine. Due to their robustness to parameters variations and external disturbances, sliding mode controllers are widely used for the control of electrical drives. The main interest of using FPGAs to implement such controllers is the very important reduction of the execution...
In this paper the torque and speed sensorless induction motor (IM) control is presented. The main idea consists in utilizing the best qualities of the both nonlinear structures of the motor observer and the current controller. Motor observer is based on flux error between modeled and measured quantities. In addition, the rotor flux observer is using combination of the feedforward and feedback terms...
