Description: To improve the boiler drum level control system of a power plant, the three challenging issues encountered include (1)
effect of ‘‘false water level’’, (2) controller parameter mismatches due to variant working conditions and (3) signal noise
caused by uncertainties of drum level. In this paper, based on analyses of the drum level signal, an adaptive derivative
action is presented to monitor steam flow, and thus, the effect of ‘‘false water level’’ is weakened. The uncertainties of
parameter mismatches and noise are predicted by developing a Grey predictor based algorithm (GPBA). In order to
resolve the three problems and further control performance, an adaptive technique is combined with the GPBA to develop
an adaptive Grey predictor based method. Finally, concrete simulations give that the proposed method has obvious superiority
over conventional methods. Platform: |

Description: In this project we have used Dynamic Matrix Control algorithm which is a strategy used in predictive control for predicting the proceeding control actions in a control system.
our plant is a Drum-type boiler-turbine system that is mainly used in power plants.
in this work DMC is used to prepare the control action needed to control the outlets of the different valves to control steam,water flow and the fuel consumption in an optimal way considering some observation parameters,such as water level,and steam pressure.-In this project we have used Dynamic Matrix Control algorithm which is a strategy used in predictive control for predicting the proceeding control actions in a control system.

Description: 仿真曲线可以看出，神经网络PID和模糊PID的响应速度比常规PID控制快，而且系统的调整时间很短，没有超调。神经网络PID与模糊PID的控制效果相同，都能在极短的时间内，消除偏差，快速地克服偏差的影响，改善了系统动态特性，因此说明神经网络PID和模糊PID对锅炉汽包水位的控制效果要优于常规PID控制。-Simulation curve can be seen, PID and fuzzy PID neural network response speed faster than the conventional PID control, and adjust the system time is very short, there is no overshoot.
