真空断路器循迹控制
Path Tracking Control of Vacuum Circuit Breaker
摘要
Abstract
A fuzzy algorithm with self-turning function was proposed in this paper to make Permanent Magnetic Actuator (PMA) move along with the given displacement curve. Then the closing time of PMA is stable and the precision of phase-selection operation is improved. The deviation of displacement, caused by the variation of capacitor voltage and ambient temperature, can be corrected by the algorithm in real time. So PMA can still move along with the given displacement curve. The standard displacement curve and the basic parameters were obtained by the high-voltage switch testing equipment and hardware system DSP2812 respectively. Meanwhile, a closed-loop system, considering free-wheeling process of coil, was established in the software Matlab to verify the feasibility of the algorithm when the voltage of capacitor varied. In addition, a large number of tracing experiments have been done on the breakers and the results proved that closing time of breaker can be stabilized within±0.5ms under the condition of changing capacitor voltage and ambient temperature.关键词
