Abstract

To solve the coupling problem in aero-engine multivariable control system

a new PID(proportion integration differentiation) decoupling controller based on support vector machines(SVM) was proposed.The SVM was applied to identify the aero-engine model

and then linearized to extract the instantaneous linear model.The PID parameter was obtained based on the linear model.The convergence of PID decoupling controller was proved with the help of Lyapunov stability theorem.Simulation results of certain aero-engine system demonstrate the effectiveness and feasibility of the PID decoupling controller based on SVM.
