In this note, a new robust nonlinear output feedback variable structure controller is first systematically and generally designed for the output control of more affine uncertain nonlinear systems with ... For practical application the continuous implementation of the control input is made by the modified saturation function. ... Pan, Kumar, Liu, and Furuta designed the nonlinear time varying sliding sector for a single input nonlinear time varying input affine system in the form of state dependent linear time variant system with ...doi:10.7471/ikeee.2014.18.2.206 fatcat:4odxc436ova6deptyuzvh5xfc4

We prove that the cascade connection of two systems is unobservable if there is a pole-zero cancellation between the spectrum of the first system and the zeros of the second system. ...
This paper considers the problem of designing static-state feedback laws for output regulation of square affine nonlinear systems. ... In the case where the input-output decoupling matrix is rankdegenerate, it is shown that a static-state control law for output regulation can be constructed as long as the system can be input-output decoupled ... For a general affine nonlinear system of the form (1) it is unlikely that a singularity will occur exactly on the zero-output-level set. ...doi:10.1016/s0005-1098(97)00052-6 fatcat:v6o4fonaobb6fncqagxhzayhge

It is well known that both the poles and zeros of a discrete system can be arbitrarily assigned if the zero-order hold (ZOH) input is modifed to allow appropriate inter-sampling-time input variation. ... Finally, an illustration is given to demonstrate the proposed method for the assignment of discretization zeros in discrete time systems. ...
