Operator-based nonlinear feedback control design using robust right coprime factorization

Operator-based nonlinear feedback control design using robust right coprime factorization
In this note, robust stabilization and tracking performance of operator based nonlinear feedback control systems are studied by using robust right coprime factorization. Specifically, a new condition of robust right coprime factorization of nonlinear systems with unknown bounded perturbations is derived.

Robust Control for Nonlinear Systems Using Passivity-Based Robust Right Coprime Factorization

IEEE Transactions on Automatic Control, 2012
The robust control for nonlinear feedback system with unknown perturbations is discussed based on the robust right coprime factorization and passivity property. Firstly, based on passivity property, the right factorization of the perturbed plant is realized.

Parameterization of stabilizing controllers with either right- or left-coprime factorization

IEEE Transactions on Automatic Control, 2002
A parameterization method of stabilizing controllers that requires only one of right-/left-coprime factorizations is presented. As an illustrative model, we will consider the multidimensional system with structural stability, for which it is not yet known in general whether or not a doubly coprime factorization always exists.

Robust control for uncertain nonlinear feedback system using operator-based right coprime factorization

IEEE/CAA Journal of Automatica Sinica, 2019
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, 2011
The 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 ...
