To obtain perfect performances of the main steam temperature control system, a new scheme is proposed. The scheme substitutes fuzzy self-tuning PID controller for the main regulator of cascade control system. The controller is composed of fuzzy controller and PID controller. According to the error and error rate of the control system and fuzzy control(More)
This paper mainly introduces the extraction methods about the boiler flame area of boundary layer. Using the binarization arithmetics, CCD image data will become a binary 2 direction matrix. Based on the ARM of the system speed processing, ARM will extraction the boiler flame area boundary layer position. Unexploded area, Fire area, Combustion area of the(More)
The ball mill pulverizing system with multi-variable, strong coupLing, large inertia and time-varying etc characteristics, long-term since difficult to input automatic control, therefore become electric power industry automatic control research hot spot problems. This paper studied and analyzed in detail the working principle of the ball mill pulverizing(More)
