The Mathematical Model

The mathematical model of the ship autopilot system is established which centering on marine hydraulic steering gear, based on the Nomoto ship motion model, and considered the influence of wind, wave, flow and other environmental factors on ship course angle. Depend on this model, the physical-digital hybrid simulation autopilot simulator is developed. This simulator has all of the operating functions of the ship steering system, it can not only simulate the turbine engine working scenarios, but also dynamically display the operation process, and the simulator is applicable to the ship track control research and crew training work.

Wheel Vibration

We focus on the antivibration controller design problem for electrical power steering (EPS) systems. The EPS system has significant advantages over the traditional hydraulic steering system. However, the improper motor controller design would lead to the steering wheel vibration. Therefore, it is necessary to investigate the antivibration control strategy. For the implementation study, we also present the motor driver design and the software design which is used to monitor the sensors and the control signal. Based on the investigation on the regular assistant algorithm, we summarize the difficulties and problems encountered by the regular algorithm. After that, in order to improve the performance of antivibration and the human-like steering feeling, we propose a new assistant strategy for the EPS. The experiment results of the bench test illustrate the effectiveness and flexibility of the proposed control strategy. Compared with the regular controller, the proposed antivibration control reduces the vibration of the steering wheel a lot.

Hydraulic Power Steering

Conventional hydraulic steering system has the problems of "low-speed heavy, high-speed flight" and energy-wasting when steering, the main reason is after the system is designed, the power characteristics are fixed. To solve this problem it is necessary to achieve the power characteristics of changing power steering system according to speed of vehicles, in order to offer the power that matches the speed. Using vehicle speed sensor signal to control pilot solenoid unloading valve to regulate the pressure of hydraulic system, can achieve the regulation of power characteristics, this article is based on such idea to design variable hydraulic power steering system for hydraulic power steering system of light trucks.
