| Abstract: | By taking the method of differential geometry as a tool,a new design is proposed in this paper,aiming at the features that the relationship of output variables is implicit functions with unknown time-varying parameters and the system is nonlinear multivariable.This paper presents a method of adaptive decoupling-linearization and nonlinear PID-controller for a nonlinear MIMO process,whose relative order is equal to one.This method is proved to be applicable to the nonlinear system with implicit outputs.The s... |
