Advanced Control Algorithms Based On Matlab And Mcgs Research Applications In Industrial Processes

The beginning of the thesis presents the title's meaning and the searching background, analyzes the application of generated software in industry monitoring and controlling system presently, summarizes their advantages and limitations, with emphasis on Monitor and Control Generated System which is been widely used at present. It discusses the advantages of manipulation of simple, efficient and fast and the limitations of simple arithmetic and weak robustness. It can just use the simple PID arithmetic. It presents the advanced arithmetic which can be used in the factual controlling process, proposes the thought of further developing latency of MCGS generated software.Then the thesis presents the theory of two kinds of advanced arithmetic particularly, analyzes the rationale and work process of control arithmetic of fuzzy adapted PID and BP neural network, and brings improved step.The thesis discusses the whole process of the application of the advanced control arithmetic between the control process, based on MATLAB and MCGS, presents the emphases and difficulties in application particularly, the compiling and embedding of arithmetic, the collection of real-time data etc. Firstly, it discusses the interface between MATLAB and external program, analyzes some kinds of method at present and takes COM to carry out the MATLAB exterior transfer. Secondly it designs the fuzzy adapted PID controller and BP neural network controller. Finally it particularly presents the process of compiling the MCGS controller in Visual Basic.The thesis introduces the process of linking the self-made controller and generated software and the control effect, analyzes the practicability from the effect of running speed, controlling effect, reliability and hardware demand.To sum up, MCGS is an application plant, MATLAB is the tool of math analyzing, data processing and arithmetic exploiting, and VB is the connection between them. An intelligent control system which is set up in laboratory environment makes use of the merits of MATLAB in compiling arithmetic, as well as the generated software's advantage of developing application. The generated software imports the advanced arithmetic, not only the simple PID or hardware controllers. So its capabilities have greatly improved, and the advanced arithmetic has been used more widely.The result of experiments shows that the designing project of this system is feasible, especially it has short developing period, stable control, advanced control arithmetic and further developing latency.
