Problems solved by technology
[0003] The traditional hydraulic control system mainly uses analog signals to control the operation of the steering gear. In the application of actual ships, there are problems such as insufficient precision, low product reliability, difficult maintenance, and cumbersome on-site debugging. For example, in the commonly used hydraulic servo In the control system, the fixed PID (proportional-integral-derivative) control parameters determine the performance of the system. In traditional systems, there is often a lack of adjustment gain link or the debugging process is complicated. Potentiometers are used to modify parameters, which greatly hinders the improvement of installation and debugging efficiency

The embodiment of the invention provides a control method and system for a ship steering engine. The method comprises: obtaining analog signals of a sensor of the ship steering engine; carrying out digital processing on the analog signal to obtain a processed digital signal; acquiring a steering order signal of the steering engine; obtaining a control error signal according to the processed digital signal and the rudder signal; and controlling the steering engine to steer according to the control error signal. According to the scheme, the servo valve of the steering engine is controlled according to the sensor information, so that the reliability and maintainability of the system are improved, the field debugging method is simplified, and the modularization and universality of the system are enhanced.
Description
technical field [0001] The invention relates to the technical field of ship steering gear control, in particular to a control method and system for a ship steering gear. Background technique [0002] In the field of ships, with the continuous improvement of the requirements for navigation safety, ship size and navigation performance, the previous simple human rudder consisting of rudder blades and tillers is far from being able to meet the requirements. In this case, electric steering gears and hydraulic steering gears have appeared one after another, which reduces labor intensity and effectively ensures the reliability of navigation. For now, the most widely used steering control system, the core of which is mainly to control the operation of the steering gear by solenoid valves or hydraulic servo valves. However, traditional hydraulic servo systems are mostly realized by pure analog electronic components and digital-analog hybrid methods. The main realization principle is...
