Cascade Speed Regulation Of Wround Rotor Motor By Single-chip Controller Of Fuzzy Control

Three phase-asychronous wround motor is widely used in many aspects of industrial and angriculture served as electrical servo systems. The traditional methods of speed-regulation have many shortcomings such as complexity of equipment, low reliability, narrow adjustable range, low control precision and efficiency and so on. This thesis focused its attention on the concrete application of fuzzy control technology to avoid above shortages in speed-regulation of 2. 2kw wround motor, also has a useful discussion about the improvement of efficiency.In this system, we applied three-phase-zero-style circuit and 87C52 single-chip controller as the fuzzy controller. Based on the control object, we employed the "adjustable factors of fuzzy control rule" to realize the software control method and normalize the circuit to decrease the cost and enhance the reliability of the system. What's more we can accomplish complexer control.The experiment's result shows that the scheme is reliable and has an advantage in application.
