Steady state performance of a single phase induction motor fed by a direct AC-AC converter

In this paper, a novel energy-efficient single-phase induction motor with three parallel-connected stator windings and two external capacitors has been proposed. By selecting the appropriate capacitors, the currents in the three windings will be approximately symmetric at rated load, thus high rated efficiency can be obtained. Based on the symmetrical component method, the condition for balanced operation is analyzed and the method for determining the requested capacitances is also obtained. The approach for calculating the steady-state performance is proposed.

Repetitive Controller

A PRE control scheme in single-phase inverter is adopted, namely connecting the proportional component with repetitive controller in parallel. This control scheme not only retains the characteristics of fast dynamic response from proportion link ,but also absorbs the advantages of no steady-state error in repetitive control .When the system is in stable operation condition, repetitive controller is used to resist periodic disturbance and thus improve the steady-state performance. Contrarily, the proportional component can feel mutation of input error and produce accommodation immediately to ensure the systems fast speed of response .The comprehensive theoretical analysis of this control strategy is given, and the system is designed in Matlab based on this theory, besides, the control scheme is achieved in the DSP platform by using digital control algorithm. Simulation and experimental results prove that the proposed scheme can achieve good dynamic and steady-state performance.

Steady State Performance

In the present study, the current control method of the model predictive control is applied to the field-oriented control induction motor. The augmentation model of the motor is initially established based on the stator current equation, which performs the current predictive control and formulates the new cost function by means of tracking error. Then, the influence of parameter error on the current control stability in the prediction model is analysed, and the current static error is corrected according to the correlation between the input and feedback. Finally, a simple and effective three-vector control strategy is proposed. Moreover, three adjacent basic voltage vectors are utilized, and then six candidate voltage vectors are synthesized in each sector to replace eight basic voltage vectors in the conventional model predictive control (MPC). The obtained results show that synthesized vectors, which have arbitrary amplitude and direction, significantly expand the coverage of the system’s control set, reduce the torque and flux pulsation in the conventional MPC, and improve the steady-state performance of the system. Finally, the dSPACE platform is employed to validate the performed experiment. It is concluded that the proposed method can reduce the torque and flux pulse, perform the induction motor current control, and improve the steady-state performance of the system.
