Research on Optimal Control for the Vehicle Suspension Based on the Simulated Annealing Algorithm

摘要：

　　A method is designed to optimize the weight matrix of the LQR controller by using the simulated annealing algorithm.This method utilizes the random searching characteristics of the algorithm to optimize the weight matrices with the target function of suspension performance indexes.This method improves the design efficiency and control performance of the LQR control,and solves the problem of the LQR controller when defining the weight matrices.And a simulation is provided for vehicle active chassis control.The result shows that the active suspension using LQR optimized by the genetic algorithm compared to the chassis controlled by the normal LQR and the passive one,shows better performance.Meanwhile,the problem of defining the weight matrices is greatly solved.
