In LN2000 distributed control system developed by ourselves, the module with adaptive control based on a neuron is designed and developed. Input variables, output variables and parameters of the module are introduced particularly, and the method of non-turbulent switch from manual control to automatic control is discussed. According to main steam temperature plant in thermal power plant, a cascade control system is established with the adaptive controller based on a neuron, and real time simulation is carried out with LN2000 distributed control system platform. Tracking performance and strong robustness of the system are proved by real time simulation results.
