Abstract

Steering gear is the most important part of the surface ship steering system. The principle of steering system, the composition, function and working principle of the hydraulic steering gear are introduced in this paper. The transfer functions of each step in hydraulic steering gear are deduced. The mathematical model of the hydraulic steering gear is established and simulated with the software of Matlab-Simulink. The results indicate that the response and the signal tracking performance of the system are improved under the PID controls parameter.
