摘要：
Parameter uncertainty is an inherent characteristic of control systems. To assess the impact of parameter uncertainty on the system, the dynamic performance assessment with uncertainty quantification and sensitivity analysis is proposed. The input sample set is obtained by Wilks' method and Latin hypercube sampling, then dynamic simulation and statistics are used to realize the uncertainty quantification of output parameters and the identification of key output parameters. The central composite design and second-order polynomial are used to build the agent model for the Sobol's method. Taking ...
