According to the question of linear continuous time invariant system quadratic regulator, the paper proposes a control program,utilizing internal model principles to build a new model to perform tracking control with no steady error and utilizing quadratic optimum control principles to calculate optimum control and through select weighted matrix to perform the dynamic response of system.The analysis shows that this is a robust control.According to the requirements of a practical controlled object,the paper designs and simulates the system,and the simulated results show that this control method entirely meets the requirements of design.
