基于改进型滑模观测器的飞轮储能系统控制方法
Research on FESS Control Based on the Improved Sliding-mode Observer
摘要
Abstract
By analyzing the error between the actual angle and the sliding-mode observer’s estimated angle when a flywheel motor operates at a high speed, an angle error elimination method compensating a constant lag angle of an adaptive low-pass filter whose cutoff frequency equals to the motor electrical frequency was proposed, and then the sliding-mode observer was improved. The stability condition was derived after conducting stability analysis of the improved sliding-mode observer. In order to realize the flywheel motor sensorless control at the whole speed range, a current closed-loop control based on emulated angle was used at startup and low speeds, then the control was switched to sliding mode variable structure control when the flywheel speed increases to a set value. The FESS charge and discharge control algorithm based on the improved sliding-mode observer was presented. In charge and standby mode, the dual closed-loop control strategy employing an outer speed loop and an inner current loop was used, while in discharge mode, the dual closed-loop control strategy employing an outer voltage loop and an inner current loop was used. Experiments in startup, charge, standby and discharge mode have been conducted. Experimental results validate the correctness and effectiveness of the FESS control algorithm based on the improved sliding-mode observer.关键词
