In the severe cold area,the severe environments have bad impacts on the use of the platform door system of rail transit,so it is necessary to adopt the preheating control system to ensure the stable operation of the equipment.In order to solve the problem that the platform door preheating control system has diffi culties to use the accurate mathematical model,and the system control parameters are difficult to set,which leads to the instability of the preheating effect,the reduction of the system security and reliability,this paper discusses the traditional PID(proportion,integral,differential)control,fuzzy control and RBF neural network to build an intelligent and effi cient control algorithm,and the simulation and experiment show that the algorithm realizes the automatic and fast iterative optimization of preheating control parameters,has better temperature control effect,improving the dynamic control performance of traditional PID control algorithm and the control stability of non-linear objects,and providing certain practical application reference value.
