Abstract

The invention belongs to the crossing field of machinery and control, and discloses a meta-action unit rotating speed control method based on a simulated annealing algorithm and a fuzzy PID, which comprises the following steps of: firstly, before rotating speed control, decomposing a whole machine into a subsystem, and then decomposing the subsystem into a meta-action unit for control; collecting the rotating speed of a worm rotating element action unit through a speed sensor, setting the rotating speed of a motor through a controller, designing a control rule table, a fuzzy domain of discourse, a fuzzy language value and a membership function of a fuzzy ID controller algorithm, and achieving setting of an integral coefficient and a differential coefficient; intelligently optimizing a scale factor of a rotating speed P controller by using a simulated annealing algorithm, and determining an optimal value by combining a PID cut-and-try method, so that the rotating speed of a worm rotating element action unit can be accurately controlled, good dynamic and static characteristics are achieved, and the stability of a motor during rotation is improved.
