Operator-based robust right coprime factorization design for planar gantry crane

2010 IEEE International Conference on Mechatronics and Automation, 2010
In this paper, a nonlinear robust control scheme is considered for a planar gantry crane system. The influence of motion friction and viscous friction of the linear motor and viscous friction of the cable is investigated under different operating conditions.

An explicit solution to polynomial matrix right coprime factorization with application in eigenstructure assignment

Journal of Control Theory and Applications, 2006
Summary: In this paper, an explicit solution to polynomial matrix right coprime factorization of input-state transfer function is obtained in terms of the Krylov matrix and the Pseudo-controllability indices of the pair of coefficient matrices. The proposed approach only needs to solve a series of linear equations.

Tracking control of a class of time-varying nonlinear systems based on right coprime factorization

Proceedings of the 2013 International Conference on Advanced Mechatronic Systems, 2013
We consider a class of nonlinear continuous-time time-varying plants with a state-space description which has a uniformly completely controllable linear part. For this class of system, we obtain by calculation a right factorization. In the case where the state is available for feedback, we obtain a normalized right-coprime factorization with some of ...

On the use of right-coprime factorizations in distributed feedback systems containing unstable subsystems

IEEE Transactions on Circuits and Systems, 1978
In this paper, we prove that every rational transfer function matrix has a right-coprime factorization in {\cal Q}^{n \times n} , and that a right-coprime factorization contains all the information about the domain and range of an unstable operator. We also derive a general necessary and sufficient condition for feedback stability that is applicable ...

Right coprime factorizations using system upper Hessenberg forms-the multi-input system case

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
Based on a method for right coprime factorizations of linear systems using matrix elementary transformations, it is shown that a very simple iteration formula exists for right coprime factorizations of multi-input linear systems in system upper Hessenberg forms.
