Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The block diagram of a conventional PID control system is as follows: figure 2 shown. The control system is composed of PID controller and controlled object. Among them, r(t) is the given value, y(t) is the feedback value of the system, and the given value and the feedback value constitute the control deviation e(t)=r(t)-y(t); e(t) is used as PID The input of the controller, u(t) is used as the output of the PID controller and the input of the controlled object, so the control law of the PID controller is:

[0025] u ( t ) = K P · e ( t ) + K I Σ j = 0 ...

Abstract

The invention discloses a dynamic PID (proportional integral derivative) control based hydroviscous variable speed clutch control method. Operation work conditions are divided into a starting state and an operation state, control oil pressure is taken as a direct control object in a starting state, the rotating speed of a driven shaft is taken as a direct control object in the operation state, and dynamic change of PID parameters is realized in the operation state. Compared with the prior art, the dynamic PID control based hydroviscous variable speed clutch control method has the advantages of good dynamic response, low probability of overshooting, short adjustment time, low probability of shaking and the like.

Description

technical field [0001] The invention relates to a control method of a fluid viscous speed regulating clutch. Background technique [0002] The hydraulic viscous clutch is a new type of transmission developed in the 1970s and widely used. It relies on the viscosity of the liquid and the shearing effect of the oil film to transmit torque and adjust the speed. By adjusting and controlling the oil pressure, the thickness of the oil film between the main and driven friction plates, that is, the degree of compression, is changed. Realize stepless speed regulation of driven shaft speed. The hydraulic viscous speed clutch is mainly used in fan, water pump, belt conveyor and special ship power, such as figure 1 As shown, the speed regulation control system of the fluid viscous speed regulation clutch 90 is mainly composed of an electro-hydraulic proportional valve 91, a rotational speed sensor 92, an electric controller 93, etc., wherein the electric controller 93 is the core of th...
