Application of Robust H_∞Guaranteed Cost Control to Sewage Treatment System

Taking the sewage treatment system of a certain treatment plant for example,the model of robust H_∞guaranteed cost controller is designed.Dynamic property analysis is carried out to confirm the state feedback control strategy,and the system stability is improved.Finally,the designed robust H_∞guaranteed cost controller is applied to simulation,and simulation results show that the method designed is feasible and effective.
