  • According to uncertain characteristics of modern control system, a new robust control method based on guardian maps theory was proposed. In light of guardian maps theory, the constraints between the controller gain parameters and the closed loop system poles were set up by this algorithm. By the closed loop system poles assignment, the dynamic characteristics and the steady performances were to meet the expected performance requirements. The controller structure was fixed. As long as an initial gain parameter was given, the robust control of the system can be realized. Simulation results show that this algorithm can adaptively obtain the control gain parameters and meet the control requirements all along the entire domain for the second order system model with parameter. Meanwhlie,the Monte Carlo random experiment shows that the control gain parameters still satisfy the requirements of system control performance, so as to ensure the robustness of the control process under the random variation of system parameters.
