Fuzzy controller of variable pitch wind driven generator based on interpolation algorithm

In the control system, the application of basic fuzzy controller method, steady-state quality is not very good, steady-state accuracy is not high. The main reason is the controller regulation dead zone caused by rough quantitative stepping of calculation by error E and error slewing rate Ec, and the too rough regulation formed by the stepping controller output. wind driven generator difficult to meet the requirement of control. For the above reasons, The method unifies interpolation calculation to the fuzzy judgement process, simplified the design of fuzzy control list. Improved the output of fuzzy control, eliminated the dead area of adjustment, reduced the requirement of output coefficient scale to a large extent, improved the control quality, especially steady-state quality. The fuzzy controller improvement realizes the method improvement, without any other structure, stability and reliability, improved the efficiency from 48% enhances to 62%. Further improvement need for further work.
