Research On MFAC And It's Simulation Of Thermal Processes In Power Plant

Compared with the tradiational control methods based on models,model free adaptive control have more original in theory .MFAC is an advanced control strategy with excellent self-turn and robustness. Some complex systems used this methods is very concise and effective in application.Development with intelligence control,learning control and date mining,and MFAC mostly attended day by day.Considering the basic of MFAC,pointed out the drawback of MFAC and improved in theory,some useful results is obatained.The simulation research combined with the thermal processes in power plant.Some general simulator of MFAC are developed and implemented in the Simulink environment,such as SISO-MFAC,Feedforward MFAC, Anti-delay MFAC, HIS-MFAC.The thesis is organized as follows:Chapter 1.Chiefly introduces the MFAC background and meanings;Chapter 2.first gives the research on the MFAC and the stability of MFAC is proved;Chapter 3. We proposed the generalized universal model based on MFAC,give the direct adaptive predictive algorithm;4.The research on the thermal processes in power plant,especially introduces severl control schemes such as superheated steam temperature systems and water lever systems;Chapter 5.Proposed model-free adaptive with human-simulated intelligent control and simulation in superheated steam temperature systems, Characteristic information of dynamic process is used to heuristic and instinct inference in HSIC, and modifying the penalty factor in MFAC continuously. MFAC is used precise control directly. also given double sample rate MFA control schemes , Proportion control with high sample rate is used in inner loop to stable systems. MFAC with feedback compensation is adopted in outer loop,which can eliminate the static error.computer simulation in water lever of a Drum Boiler Generator.results show this schemes is advanced in theory and effective in application.At last, conclusions of the thesis andthe further research topics.
