A simple control structure in servo system is occasionally needed for simple industrial application which precise and high control performance is not exessively important so that the cost production can be reduced efficiently.Simplified vector control,which has simple control structure,is utilized as the permanent magnet synchronous motor control algorithm and genetic algorithm is used to tune three PI controllers used in simplified vector control.The control performance is obtained from simulation and investigated to verify the feasibility of the algorithm to be applied in the real application.Simulation results show that the speed and torque responses of the system in both continuous time and discrete time can achieve good performances.Furthermore,simplified vector control combined with genetic algorithm has a similar performance with conventional field oriented control algorithm and possible to be realized into the real simple application in the future.
