The coordinate throttle and brake control is one of the main challenges of vehicle longitudinal control. The main difficulties are due to the complexity and uncertainty of the vehicle dynamics, and the necessity of the switching between throttles and brakes. A hierarchical control system is proposed, in which an upper level controller determines the desired speed/acceleration for the controlled vehicle,...
When ship docks at harbor or other sea area, both the robustness and dynamic properties of course control system are required strictly. Because the model parameters are relative to the speed and load of the ship, it is difficult to design a good controller based on the ship model. This paper combines internal model control with fuzzy neural network to design a course system. First, it designs a zero...
This paper describes the dynamical uncertain systems by the Takagi-Sugeno (T-S) fuzzy dynamic model, and proposes a LMI design method of the robust fuzzy sliding mode observer by applying the robust sliding-mode observer design principle based on the singular value decomposition. Firstly, the Lyapunov function is used as the critical condition which ensures the consistent convergence of the designed...
This paper considers the sliding mode observer based actuator fault reconstruction schemes for a class of uncertain dynamic system with mismatched uncertainties. To deal with a broader class of mismatched uncertainties, we propose the novel sliding mode observer, which LMI existence conditions and some verification are given by combined with LMI methods and are primarily designed for actuator fault...
The states estimation of dynamic system plays an essential role in the fields of science research and engineering application. The designing method of robust sliding mode observers with unknown disturbance is proposed in this paper, and the novel robust sliding mode observers and the optimal sliding strategies are designed by using the simplified technique based on the singular value decomposition...
This paper discusses the designing approach of the sliding mode observers. Based on Edwards's sliding mode observer, a robust sliding mode observer is presented, and the singular value decomposition technology endows the canonical process with simplicity. Then the linear feedback gain and the nonlinear feedback gain of the robust sliding mode observer are synthetically processed by Linear Matrix Inequalities...
