A Novel Fuzzy Logic PID Algorithm for Submarine Hydraulic Rudder Control

Abstract:

According to the composition of the submarine hydraulic rudder system, the paper analyzed the different advantages and disadvantages of the rudder type, steering agencies and the hydraulic rudder control system as well as the scope of application. System steering bodies of pump control servo, variable pump displacement control system, steering control system and rudder hydrodynamic interference model were modeled. Fuzzy logic hydraulic servo parameter adjustment method is presented, and simulation analysis of the variable pump displacement control system and steering system. As the system parameter uncertainties and load disturbance, the performance impact of parameter variation and load disturbance simulation analysis.
