A Fuzzy Logical Optimal Efficiency Control of Permanent Magnet Synchronous Motor
Guang Xu Zhou(주광성),Dong-Hee Lee(이동희),Jin-Woo Ahm(안진우) 대한전기학회 2007 대한전기학회 학술대회 논문집 Vol.2007 No.4
This paper presents a fuzzy logical control method to implement an on-line optimum efficiency control for Permanent Magnet Synchronous Motor. This method real-timely adjusts the output voltage of the inverter system to achieve the optimum running efficiency of the whole system. At first, the input power is calculated during the steady state in the process of efficiency optimizing. To exactly estimate the steady state of the system, this section needs check up the speed setting on timely. The second section is to calculate input power of de-bus. The exact measurement of the voltage and current is the vital point to acquire the input power. The third section is the fuzzy logic control unit, which is the key of the whole drive system. Based on the change of input power of de-bus and output voltage, the variable of output voltage is gained by the fuzzy logical unit. With the on-line optimizing, the whole system can fulfill the minimum input power of do-bus on the running state. The experimental result proves that the system applied the adjustable V/f control method and the efficiency-optimizing unit possesses optimum efficiency, and it is a better choice for simple variable speed applications such as fans and pump.
