Design And Realization Of Detect Malfunction System Of Gyropilot

one automatic pilots which have equipped universally in our naval ships are our naval principal type of automatic pilot. one auto-pilot is welcomed by the army men on warships for its simple design and easy use. Though a great deal of one auto-pilot have been equipped in navy, there is still a lack of special test device on the one automatic pilot. And how to measure performance parameters of one auto-pilot after regular servicing is remained as a question.In this thesis, the one auto-pilot is thoroughly analyzed based on the task of The Fault Detection Device for Model one Autopilot, a test platform for one autopilot has been built, and a rapid test method for the PID parameters of auto-pilot has been presented and proved feasible.This thesis concerns on several aspects listed below:1. The analysis of the object. The research object, model one auto-pilot system, has been disassembled, the features of the object has been ascertained, and the math model and the physics model of the object has been built.2. The researches on the FDD theory. After the study on theories of fault detection and diagnosis, the method that planed to used on the FDD device for the auto-pilot system has been decided.3. Design and build the hardware of the test platform. Based on the demand of FDD theory, a FDD test platform for the auto-pilot system with MCU intelligent control cell has been built up. Its hardware design can meet the needs of the test, and its function can be easily updated by rewrite the software.4. Program. Mainly included the program of the test platform and the program of the fault detection, they work together to realize the FDD function.5. Experiments. In this part, an experiment has been designed to testify the fault detection ability of the test platform and the veracity of the PID parameters test method.
