Fluid couplings Speed ​​Control System

Large hydraulic pump and fan speed control key technologies ", to apply to the BOF gas blower speed fluid coupling speed as an example to study. Pair of hydraulic coupling system dynamically adjusts the fan speed control feature analysis of the mathematical model derived; fuzzy-PID control method to establish the fan speed hydraulic coupling automatic control system, and the system is simulated. paper, the main contents are as follows: (a) on the converter refining hydraulic coupling steel gas blower speed control system for dynamic regulation characteristics analysis, the fan speed  Hydraulic adapters  coupling system is a part of inertia link plus a delay system with variable parameters expressed. (2) consider the governor hydraulic coupling the mathematical model and fuzzy, PID control advantages and disadvantages, the use of fuzzy-PID control method as a dual speed hydraulic coupling control method and designed the hydraulic coupling speed control system of fuzzy controller, PID control devices and mode switch. (3) in the computer software to create a fluid coupling fan speed mode fuzzy-PID control system model, compared with a single PID control simulation
