Abstract: An α th-order inversed decoupling control method based on least square support
vector machines (LS-SVM) is presented to resolve the difficulties of inverse modeling with the
traditional inverse control methods in this paper. The nonlinear offline inverse model of plant is
built by LS-SVM, which is cascaded before the original system to decouple a complex
multivariable input and output system into several independent single input single output
pseudo-linear sub-systems. In order to make it have better robustness, with single neuron
adaptive PID as subsystem additional linear controller to constitute a closed-loop system. The
characteristics of combustion system of circulating fluidized bed boilers also are analyzed and
control system based on presented methods is presented. The simulation results demonstrated
that the presented method could achieve accurate decoupling control with robustness. © 2012
