Permanent Magnet Linear Brushless DC Motor position control system based on single neuron

In this paper, the method of single neuron PID control for Permanent Magnet Linear Brushless DC Motor(PMLBDCM) is addressed. For the poor performance of the system of anti-disturbance features, a disturbance observer to increase the system robustness of PMLBDCM drive system is designed. As the demonstration of the results, the system robustness of the driver is increased and function of the motor can be more accurate and quicker.

Simulation of Charge-Discharge Control Strategy of Bi-directional Inverter in Grid-Connected Mode

Bi-directional inverter is a device, which can be used in charging or discharging battery in a wind-solar-diesel hybrid power system based on pure AC bus. In this paper, through the study on charge-discharge control of bi-directional inverter in grid-connected mode, the double-loop control strategy has been used. And considering the effects of grid voltage fluctuation and load switching on voltage and current in the process of charge-discharge, the fuzzy control is introduced in the control system to improve the performance of the disturbance rejection and reliability and extend battery service life. The feasibility and validity of this control strategy are proved by simulating.

Improved deadbeat control algorithm based on hybrid prediction strategy of micro-source inverter with harmonic compensation

A micro-source inverter which is connected with the microgrid is studied in this paper, and it has the function of harmonic compensation and power supply. Considering the output power of the generating unit (GU) and the load are unsteady, an improved deadbeat control algorithm (DCA) based on a novel hybrid prediction strategy (HPS) is proposed. The improved DCA can solve the delay problem of the conventional deadbeat control and improve the precision of the whole control system. Then the simulation shows that the improved DCA can be correctly and effectively applied into the control of the micro-source inverter.
