Abstract

A digital fuzzy controller used on speed regulation clutch of viscous liquid is a speed regulator connected in external with three analog input interfaces, two digital interfaces, two pulse interfaces, RS485 interface, keyboard input and display screen. The said speed regulator uses one pulse interface to input speed signal detected out from driven shaft of speed regulation clutch and uses another pulse interface to input speed signal detected out from driving shaft of said clutch for applying photoelectric rotary coder to measure speed.

Description

technical field [0001] The invention relates to a controller for a viscous liquid speed-regulating clutch, in particular to a digital fuzzy controller for a viscous liquid speed-regulating clutch. Background technique [0002] Liquid viscous transmission is a new form of fluid transmission developed in the mid-1970s. It uses the oil film shear force between the main and driven parts to transmit power, also known as oil film shear transmission. It is a fluid transmission technology. important areas of development. [0003] Liquid viscous clutch, also known as Omega clutch, utilizes liquid viscosity and oil film shearing to transmit torque, and realizes stepless speed regulation by changing the distance between friction pairs. It is widely used in various occasions that require stepless speed regulation. For example, under heavy load conditions, "soft start" can be implemented to gradually overcome the inertia of the entire system and start smoothly so as to greatly reduce th...
