通信故障下蒸汽发生器水位MPC/DDPG切换控制
MPC/DDPG switching control for steam generator water level under communication failures
摘要
Abstract
Considering the complex factors of nuclear power steam generator system,such as unknown communication faults and variable working conditions,a model prediction/data-driven switching con-trol method for steam generator water level was proposed.First,a deep deterministic policy gradient(DDPG)controller was designed,which includes state parameter selection,action parameter design,re-ward function design,was done condition design and network design,etc.The DDPG controller oper-ates normally when there were no communication faults in the steam generator control system.On this basis,a model predictive control(MPC)predictive compensation controller was designed to resist communication failures.The system was switched to the MPC controller to compensate for the lost data when communication failures occurred.The simulation results show that the MPC/DDPG switching controller of the steam generator water level can obtain a good control performance under the typical external inputs.They also show good stability and security under unknown failures.关键词
