A high gain observer is proposed for a class of nonlinear systems involving some uncertainties. In the absence of the uncertainties, the considered class of systems becomes a canonical form that characterizes a class of uniformly observable systems and the observation error exponentially converges to zero. In the presence of uncertainties, it is shown that the observation error can be made as small...
For a class of nonlinear MIMO system, a novel decoupling control method was proposed. Firstly, equivalent input of each subsystem was designed using backstepping method. Then, the total uncertainties including coupling effect, external disturbance and parameter time-varying of each subsystem was estimated via an ESO, and the estimated value was introduced into the backstepping controller to compensate...
In order to reduce the restrained conditions on the disturbance, a robust tracking control approach is presented based on fuzzy disturbance observer for a class of uncertain nonlinear MIMO systems. Novel parameters update laws based on Lyapunov theory and control laws are proposed to guarantee that all the signals in the system are uniformly ultimately bounded and achieve given tracking performance...
A new control design method based on signal compensation is proposed for a class of uncertain multi-input multioutput (MIMO) nonlinear systems in block-triangular form with nonlinear uncertainties, external disturbances, unknown virtual control coefficients and strongly coupled interconnections. By this method, the controller design is performed in a backstepping manner. At each step of backstepping...
In this paper a novel approach is proposed to solve a decentralized control problem to stabilize a multivariable system and attenuate the interconnections between its subsystems. To satisfy these conditions, an ut feedback controller is designed by solving an Hinfin control problem. The designed controller is applied to a practical multivariable flow-level plant to show the effectiveness of the proposed...
