U-model enhanced control of Volterra series systems

This study expands the U-model based control (U-control in short) concept and formulation, a universal model-independent framework for designing control systems, into Volterra series modelled nonlinear systems. With this framework, various Volterra series control schemes can be universally achieved with relative concise/general formulation. In techniques, this study takes U-model structure to realise U-Volterra series model conversion for model inversion and designs the invariant linear stable controller in a feedback loop to lay a basis for specifying system transient and steady state performances. Heuristically, a bench test example is used to demonstrate the effectiveness of the design procedure, as well as the routines in applications.
