Vector Control System

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.

Owing to harmful gas emissions and high accident rate of diesel engine in the coal mine trackless auxiliary transport, the spring of trackless rubber tyre electric vehicle powered by the battery pack comes. This paper considers the drive system to improve the performance of the electric vehicle. In order to adapt to the complex environment of coal mine, the analysis of basic structure for trackless rubber tyre electric vehicle was based on the three-phase AC induction motor. After elaborating the vector control theory of induction motor, the field-oriented vector control system model of trackless rubber tyre electric vehicle drive system with induction motor rotor was built in Matlab/Simulink. The simulation shows that the proposed control algorithm permits the drive system to achieve good steady and dynamic performance.

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.

Field Oriented Vector Control

This template illustrates the control system of permanent magnet synchronous motor(PMSM) which uses field oriented vector control(field oriented vector control). PMSM is a complex, strong coupling and nonlinear system. And field oriented vector control could provide good performance as well as the PI controller setted with well parameter matching. Whereas limited by the number of voltage vector, the other control method of PMSM, direct torque control, could not satisfy accurate control when the machine running with a low speed. So modulation of the whole system is built here to realize closed-loop field oriented vector control control by keeping id=0 , and the machine model and the transformation among different coordinate system are discussed. The system is verified effective and feasible.
