Feeding speed servo controller of rotary cutter without clamping

The invention discloses a feeding speed servo controller of rotary cutter without clamping, relating to a speed servo controlling system which is applied to controlling feeding speed during the rotary cut by the rotary cutter without clamping. The feeding speed servo controller of rotary cutter without clamping comprises a rotary cut model calculator of the rotary cutter without clamping, an adaptive fuzzy controller and a motor vector control unit. A speed control expectation is given by analyzing the rotary cut process of the rotary cutter without clamping, and the controller is used for realizing the servo control of the speed expectation. The invention has the characteristic that a control algorithm is advanced and practical. By deviation, the closed loop feedback input of deviation change rate is used for precisely controlling the rotary cut process of the rotary cutter without clamping. The invention adopts the adaptive fuzzy control algorithm, thus overcoming the difficulties, such as nonlinearity, no kinetic models and the like during the rotary cut of timber.
