COORDINATED MAIN CONTROL SYSTEM OF THERMAL POWER UNIT BASED ON RBFPID

Based on MATLAB software,a control strategy of RBF neural network identifying PID(RBFPID) has been designed,and adopting OPC communication mode to realize the data exchange between MATLAB and the emulation supporting software APROS of thermal power units,thereby,the developed emulation and training system of units can be used to make the control algorithms designed in MATLAB to directly participate into process control,so as to verify the practicality of control strategy RBFPID.Results of verification show that the control effectiveness of control strategy RBFPID is substantially superior to control strategy of conventional PID plus feed forward,it is convenient to debug,boasting good robustness,and can be more suitable to operation condition variation of unit.
