Most designs for heading controller adopted Taylor linearization technique and neglected its nonlinear factors. For this reason, the accuracy of heading control for autonomous underwater vehicle (AUV) was lower. In order to solve this problem and enhance the accuracy, robustness and stability for heading control system, a nonlinear model of AUV in horizontal plane was established, which include uncertainties...
A controller to suppress periodic disturbances on an industrial level control system has been designed. The plant is located in a heavily disturbed environment and has parameter uncertainties and an unknown input delay. The controller has been designed for an integral plant with unknown input delay and unknown gain to adaptively suppress disturbances at the input of the integrator. It is assumed that...
In this paper, robust adaptive neural tracking control is developed for a class of uncertain SISO nonlinear systems in a Brunovsky form with unknown nonlinear dead-zone and unknown control gain & its sign. The design is based on the principle of sliding mode control and the use of Nussbaum-type function in solving the problem of the completely unknown function control gain. A novel description...
A computer-aided method for the design of linear robust controller is studied. The control guarantees asymptotic stability of linear uncertain systems with time-varying uncertainties. The control is designed based on the possible bound of the uncertainty. Necessary and sufficient conditions for quadratic stabilisability are formulated. The controller is first designed by a two level optimisation process...
