PID Neural Network Sliding-mode Controller for Three-level Offshore Wind Power VSC-HVDC Converter
摘要
Abstract
In this paper,an online real time method that allowed for the merger of the good features of proportional-integral-derivative（PID） neural network（PIDNN） and sliding-mode variable-structure control（SMVSC） design was presented.It can solve the chatting problem when the system input parameters exists disturbances.The mathematical model of the three-level voltage source converters（VSC） in offshore wind farms high-voltage direct-current（HVDC） transmission was developed.A new SMVSC controller based on instantaneous active and reactive power error was proposed.The PIDNN can online train the network with the chosen energy function to get the global optimal solution,which gets the optimal parameter of the sliding-mode control（SMC） in real time.In addition,analytical methods based on Lyapunov function were proposed to guarantee the convergence of tracking error.Matlab simulation results show the proposed method can make system global stability,have stronger robust under system disturbance,and can be easily applied to digital control systems.关键词
