Experimental Study of Field-Oriented Vector Control System using Flux Observer Based on Robust Design Method.

In order to improve the performance of sensorless PMSM control system, an improved sliding mode observer (SMO) is proposed in this paper. To decrease the vibration of SMO, a variable switching gain which changes according to the winding currentn is adopted. To improve the estimated value of rotor position, a extra low pass filter (LPF) is employed and the linear interpolation method is used to calculate compensation value of the phase delay caused by LPF. To verify the performance of proposed SMO, a sensorless field oriented vector control system of PMSM is designed. At last, the performance of the improved SMO and the sensorless PMSM vector control system are verified by experimental results.

Orientation Bias

The paper analyzed the influence of rotor parameters changing for the induction motor vector control, and an adaptive identification method for rotor parameters was proposed. Based on Lyapunov stabilization theory, design method of adaptive identification discipline was expatiated. The model of rotor parameters adaptive identification under induction motor vector control was completed using Matlab/Simulink. The simulation results demonstrate the feasibility of the proposed method, and it can be taken as the theory and practice reference for improve the orientation bias for vector control system.

The Mathematical Model

According to the characteristics of mine fanner, the running characteristic and requirements of load was analyzed, and the fanner control system was simulated by using frequency control technology in this thesis. The speed flux double closed loop vector control system was designed by using the principle of the rotor field-oriented vector control and the mathematical model of asynchronous motor. The simulation model was simulated and analysised by MATLAB/Simulink. The result indicated that the vector control system can not only quickly responded to the change of the load torque but also have good speed control performance, and the mine fanner operation requirements was satisfied.
