The problems about guaranteeing robustness of decoupling control of induction motor and shortage of conventional robust control approaches in considering nominal and robustness performance synchronously are introduced. In order to solve these problems, principle and structure of generalized internal model control (GIMC) based two-degree-of-freedom (2DOF) is studied, the design methods of robust control...
Induction Motor (IM) speed control is an area of research that has been in prominence for some time now. In this paper, a nonlinear controller is presented for IM drives. The nonlinear controller is designed based on input-output feedback linearization control technique, combined with sliding mode control (SMC) to obtain a robust, fast and precise control of IM speed. The input-output feedback linearization...
The faulted mode of a six-phase induction machine (6PIM) denotes that the motor is working with one or more missing phases. This situation leads to torque oscillations and poor tracking behavior. Therefore, the design of a suitable robust control is a challenging task. In this way, this paper presents the application of fuzzy logic and sliding mode controls in order to obtain a high-accuracy positioning...
This paper presents an improved stator flux orientated (SFO) control strategy of induction motors. Based on coordinate transformation and stator flux orientation, a mathematical model of induction motor is derived. In this new system, the stator flux linkage is directly controlled by the d-axis component of stator voltage and in the speed control channel, the output of current controller is regarded...
