Abstract


In this thesis, derived from the, Shanghai, of Science and Technology in Colleges and Universities development fund projects - ship course integrated smart control of technical studies. The Author to participate in This topic research and wrote a The paper. Ship course automatic control system also known as the automatically rudder, it is the the a an important and indispensable equipment in the the ship system, the the emergence of of the from the the automatically rudder in the a historical the perspective of of view is to reduce the the intensity of the work of the driving personnel, reduce transportation costs, improve the sexual of the safety of transport and economic benefits. With the control technology and constantly improve the, the engineering and technical personnel put control technology introduced into the heading among the the control of established a the in order to the PID-for the controller heading to file control to a Windows system and an to obtain the a good the effect of. However, due to the the the complexity of the of the ship sailing and PID controllers itself the limitations of, the automatically rudder of the the conventional PID still exists forward to a lot of inadequacies. The The purpose of of the of the research of the this article is to propose A method of controlling a performance intelligent control be of automatically the rudder over, its the target In order to improve the based on the the control effect of of the the the PID of of the classical control theory automatically rudder. In the which the research of of to intelligent control automatically new rudder, the This article the use of the fuzzy self-tuning the the method of the PID parameters, made a some useful exploration in the the the design of aspects of of the automatically rudder, and has done a simulation research, access to the ideal control effect. The this article research is from the on the following aspects: 1. In the to the the beginning of the papers, according to the the provided by by the relevant information the real ship parameters, design the PID automatic rudder, as a the latter part of the the object of of the Comparison of Studies of. 2. The use of the fuzzy control method, in on the to the same the a the real ship object design out of a fuzzy controller, to observe its simulation results. 3. With strong A sum up the in front of two chapters the design of methods, combined with as being PID for to control the the high-steady-state accuracy of the the advantages and fuzzy of robustness of the controller and the response speed is fast characteristics of the design out of the with fuzzy-tuning by the controller of the the PD two parameters. And in the simulation to get a better results. In the the the design ship course is when the parameter self-tuning controller is fuzzy due to there is no off-the-shelf control rules of available-for-learn from, In this thesis, draws on the the fuzzy rules of the the use of in the the of other field of industrial control fuzzy self-tuning controller, and to make the appropriate according to the actual control effect rules adjustment. 4. The fuzzy control-tuning of the two-parameters theory domains When no one the mature example of of the can learn from, this paper proposes in the the adjust the parameters of of the based on the the real ship the PID controller designed, so that the control parameters to distributed in the the a a of normality on the the curve, then the appropriate expand the the the Analects domain the scope of, as a design the the whole the the of the on Fuzzy Kybernetika domain Process of the given object. In the the the results of of in the simulation test proved that the reasonableness of the of the envisaged in the. 5. End of the paper the use of the the SIMULINK toolbox provided by by the MATLAB software provided on an \Chinese Journal of Analytical results. The final simulation results show that, intelligent control on the Ship Steering control aspects of its the superiority of greatly exceeded the the automatically rudder of the of traditional control and methods of the, of its application and development of there are broad prospects. In due to to theory of intelligent control their own development is still in and constantly improve the and development of, Therefore applied to the actual needs to be done more in-depth research. The of future research of the This is also the related fields one of the an important direction for of.
