Abstract

The invention relates to an applications-oriented control device of speed-regulating clutch and a control method thereof. The device comprises a sensor unit and an electronic speed-regulating controller electrically connected with the sensor unit. The electronic speed-regulating controller comprises a signal collecting module electrically connected with the output end of the sensor unit; a mode switching signal collecting module connected with a plurality of running modes; a CPU control module electrically connected with the output ends of the signal collecting module and the mode switching signal collecting module; a ratio servo valve base point regulating circuit electrically connected to the output end of the CPU control module; and a V-I converting and current amplifying circuit electrically connected with the output end accumulating the output end of the CPU control module and the output signal of the ratio servo valve base point regulating circuit. The output end of the V-I converting and current amplifying circuit drives a ratio servo valve and controls the actions of a clutch. By using a PID control policy, the invention has the advantages of adaptation to dead zone characteristics of different ratio servo valves and wide application range.

Description

technical field [0001] The invention relates to a control device and a control method of a speed regulating clutch for various applications. Background technique [0002] As a multifunctional speed regulating device, the hydraulic viscous speed regulating clutch can be used for both land use and marine use. The power machine can be an electric motor or a diesel engine, and the working state can be completely disengaged, light-load speed regulation, heavy-load speed regulation, and power distribution. And complete combination, etc., can dynamically switch between working states, if the switching process is not handled properly, it will affect the smooth operation of the fluid viscous speed clutch. [0003] The speed control of fluid viscous speed clutch has always been a research hotspot. Some domestic manufacturers have been able to produce liquid-viscous speed-regulating clutches, but most of them are manual control or relatively simple electronic control. There are many s...
