Abstract


The induction motor has the advantages of good reliability , simple structure , corrosion resistance, good efficiency , compact structure , low price and small size , industrial servo control gear . However , the induction motor is a multi- variable , strong coupling of nonlinear systems , time-varying nonlinear coupling parameters of flux and torque induction motor control is very complicated , especially in the actual motor control system , also need to consider the interference of the hardware and the surrounding environment , and other factors , resulting in more difficult to achieve high performance induction motor control system . This study high performance induction motor control strategy , the development status of the high - performance induction motor control strategy development process and induction motors fuzzy control , analysis of the basic performance of the actual motor control system controller selection of embedded microprocessors and advantages and disadvantages. Given after the three-phase coordinate system and the coordinate system of the two-phase induction motor mathematical model , the theory expounded the basic principle of the fuzzy control and vector control for conventional PI controller parameter tuning cumbersome system robustness shortcomings paper fuzzy control technology applied to the induction motor VVVF CRI reasoning method , design parameters self -tuning fuzzy PI vector controller using Matlab simulation of induction motor control system based on fuzzy PI control and comparison, analysis of the induction motor speed control system implemented two controllers . The simulation results show that the control performance of the fuzzy control is better than conventional PI regulator . Papers on ARM-based induction motor digital control technology system elaborated microprocessor LPC2214ARM constitute a a digital induction motor speed regulation system of the method , a high-performance induction motor digital implementations details the composition of the structure and functions of the software modules of the system hardware and the reference code of the main algorithm , provides a new way of thinking for the selection and development of the actual motor controller .
