## 异步电机多电机控制算法研究

Research on Control Algorithm of Multi-Induction Motors
Abstract: Based on the direct torque control of induction motor drive system theory premise, the single inverter drive of multi motor control system, according to the vector control system of multi motor average algorithm theory, studied the derivation of the average stator flux oriented direct torque control algorithm and strategy based on. The innovation of this paper is considered in the same system of control, induction motor model, motor operating conditions of different, of all motor stator current, stator flux and electromagnetic torque of average processing, in average income of motor applied direct torque control system, so as to make all the asynchronous motor between the decrease of relative error, to run the same trend. 源`自*六)维[论*文'网www.lwfree.cn
According to the above theoretical derivation algorithm, the model of the control system is built by Psim software. The simulation experiment of the single inverter multi machine drive system based on the direct torque control is carried out, and the feasibility of the theoretical algorithm is verified according to the results of the simulation experiments.
