Abstract：Contactor is an electrical appliance used to connect and disconnect circuits. And contactors are widely used in power switching, motor control, rail transit, new energy power generation and other scenarios. During the closing process, the contact bounce collision will produce arcs, and the high-frequency long time bounce process will significantly shorten the electrical life of the contactor. It is feasible to use sensorless control to suppress contact bounce. The sensorless control technology of constant air gap contactor is studied. Position sensorless control includes position prediction and dynamic control. The equivalent magnetic circuit method and parameter identification are used to realize position prediction. On the basis of position prediction, the simulation and experimental research of dynamic control are carried out.
In order to reduce the contact bounce of the contactor, a position sensorless control method is proposed for the constant air gap contactors. The position information is extracted from the permanent magnet flux linkage through the equivalent magnetic circuit method and parameter identification, then control the actuator according to the location information. The equivalent magnetic circuit model of the electromagnetic force driving actuator (EMFA) is established, and the mapping relationship between dynamic flux linkage, displacement and current is deduced. The rationality of the mapping relationship is verified by “fixed method” and “prediction method”. The displacement, voltage and current are obtained through experiments, the flux linkage is calculated according to the experimental data, and the parameters of the displacement mapping are obtained by the method of multiple regression, and the position prediction of the contactor is completed. The predicted displacement is compared with the measured displacement, and the accuracy of position prediction is verified.
Through the parameter scanning function of the finite element model, two surfaces of driving force and flux linkage are established, and the modeling of the contactor is completed by means of interpolation, position prediction and simulation without position control are carried out. Based on the simulation model, the calculated displacement is compared with the predicted displacement, and the accuracy of displacement prediction is verified. Based on the subsection PWM control strategy, the influence of duty cycle combination on the dynamic characteristics of the contactor is analyzed. The simulation results show that the terminal speed of the contactor is reduced with the gradual reduction of the duty cycle combination.
The experimental platform is built. The experimental platform includes power module, chopper module, DSP module, contactor, sensor and voltage divider module. In the experiment, the coil current, contact bounce and contactor displacement under different duty cycle combinations are collected. The influence of duty cycle combination on closing time and bouncing time is analyzed. With the decrease of duty cycle combination, the bouncing time decreases gradually, while the closing time increases gradually. The experimental results show that the new position sensorless control method is suitable for constant air gap contactors. The accuracy of the position prediction and the effectiveness of the control method are verified.
On the basis of simulation and experiment, the following conclusions are drawn: 1) The equivalent magnetic circuit method and parameter identification can be used to predict the position of the constant air gap contactor. 2）The EMFA simulation model is established by the difference method, and the dynamic control can effectively reduce the terminal speed. 3) The experiment proves that the control method is suitable for the constant air gap contactor, and the bounce time can be reduced by 90% under the condition of subsection control.
