Considering a series of problems such as the sea wave that acts on the ship is random when ship is sailing on the sea, there exists serious nonlinearity and uncertain factors in the ship roll motion, there is strong dependence on the mathematical model of the controlled object when designing the controller for fin stabilizer system. Aiming at solving the above problems, the paper designs the cloud-model...
Aimed at the characteristics of nonlinear, strong coupling, multi-variable and natural unstable for inverted pendulum, based on information fusion technology, the state feedback gain matrix with quadratic optimal performance index is adopted as fusion function to reduce dimension of the outputs vector for double inverted pendulum, and decrease the difficulty of controller design. On this basis, a...
In order to evaluate complex system in selection of aircraft scheme, the evaluation method based on cloud model was utilized. This paper analyzed the evaluation steps based cloud model. Because of imprecision in judgment from cloud model figure in past, the measurement method of cloud comparability was introduced to judge which rating the evaluation result belongs to. Finally, the application in the...
The robust Hinfin control problem for nonlinear systems with uncertainties and impulsive effects is considered. Based on the Takagi-Sugeno (T-S) fuzzy model and the parallel distributed compensation (PDC) technique, some sufficient conditions for robust Hinfin stability are proposed and are expressed in terms of linear matrix inequalities (LMIs). Numerical example shows the control algorithm is feasible...
