Based On The Three-phase Frequency Control System Design Of The Msp430

With the quick development of intelligent control, much research has been done on theory exploring and practical application of fuzzy control. And many achievements have been got. We do some research on the development of fuzzy control and rule self-seeking-optimization fuzzy control algorithm in this thesis. This algorithm has been simulated and practically applied in induction motor variable frequency speed regulation system .The main work and research results of the thesis includes the following:l.This thesis detailedly discusses the exploitation of MCU application system based on MSP430F149, the designing method and application of each function module, including CPU module, A/D module, displaying module, keyboard module, SPWM module, interlocking and protecting circuit, driving circuit and main circuit, and so on.2.The key technology of AC speed regulating is SPWM control technology. The system adopts MSP430F149 MCU and asymmetry regular-sampling strategy to output high precision SPWM wave, consequently transducer's SPWM control is realized. The experiment proved that this way is simple and available.3.Control rule self-seeking-optimization fuzzy algorithm is used in the system. The theory base and the designing process of the algorithm are proposed in the thesis. The simulation and experimental results verify its advantages.4.The anti-jamming capability of the system is directly related to the reliability of the system. This thesis presents, in detail, the anti-jamming measures and some experiences in designing the system.The running result indicates that the system has reasonable control scheme, high operating reliability, advanced control algorithm, self-learning capability, high steady accuracy, good robust, friendly man-machine interface and convenient operation.
