Abstract: In view of problem of non-ideal control effect of energy-saving of existing asynchronous motor,the paper proposed a design scheme of comprehensive energy-saving control device based on penalty function,and established integrated optimization model of energy-saving control device.The device uses dynamic voltage regulation technology in frequency-conversion speed-regulation,and can dynamically adjust terminal voltage and frequency of the motor;it adopts penalty function algorithm to optimize power output,so as to make frequency-conversion speed-regulation system of the motor operate in the best mode,and achieve goal of energy-saving.The Matlab simulation results show that the comprehensive energysaving control device has advantages of voltage and speed regulating energy-saving,and has good energysaving effect.
