The robust control issue for uncertain nonlinear system is discussed by using the method of right coprime factorization. As it is difficult to obtain the inverse of the right factor due to the high nonlinearity, the proving of the Bezout identity becomes troublesome.

Isomorphism-based robust right coprime factorization realization for non-linear feedback systems
Proceedings of the Institution of Mechanical Engineers Part I: Journal of Systems and Control Engineering, 2011The realization of the system design problem for a non-linear feedback control system is considered by robust right coprime factorization and isomorphism. First, a feedback system with a series compensator and a feedback compensator is designed to construct a stable isomorphic subspace of the controlled plant’s input space, and then the right ...

Fractional order based robust right coprime factorization control for an inverted pendulum
2016 International Conference on Advanced Mechatronic Systems (ICAMechS), 2016Fractional order based robust right co-prime factorization control is proposed for an inverted pendulum. The mathematical model is firstly derived from Lagrange Equation and its parameters are identified by using fractional order modeling and control toolbox.

Proceedings of the 33rd Chinese Control Conference, 2014
This paper is concerned with passivity-based robust control for perturbed nonlinear feedback control systems using the operator-based right coprime factorization method. For the nonlinear feedback system with the disturbance which is described by the operator form, by designing the robust controllers and choosing the storage function, the nonlinear ...

Application of robust right coprime factorization approach to a distributed process control system
2009 IEEE International Conference on Automation and Logistics, 2009In this paper, nonlinear feedback control of a distributed process is considered by using robust right coprime factorization approach. The distributed process model is developed. The model includes a water level process model of single tank and a water flow process model for twin-tank. Then, robust right coprime factorization based nonlinear control is

In this paper, the control of water level process based on robust right coprime factorization approach is proposed. In particular, from the industrial application point of view, the implementation of the designed controller is discussed by using distributed control system (DCS). The experimental result shows the effectiveness of the proposed approach.

In this paper, an operator-based robust nonlinear multivariable tracking control for a manipulator with uncertainties is proposed by using a robust right coprime factorization approach. In general, there exist unknown modelling errors in measuring structural parameters of the manipulator and external disturbances in real situations.
