In this paper, a long divinable time evaluation and a short time prediction of some vibration signals of a turbine generator set is processed by the largest Lyapunov exponent mode. And the results show that the method is certainly accurate and reliable to predict future state of a turbine generator set. As a matter of fact, the method can be used to prediction to future running state of any other complex mechanical equipment.

Lightened on the turbine valve controller designed with feedback linearization theory and introduced nonlinear tracking-differentiator, a novel nonlinear PID valve controller was proposed. This controller can fit not only to plant with some model error and random disturbance in variable, but also to the variety of the structure and operating conditions of power system. The transient and dynamic characters of the controller are both satisfactory when big and small disturbances added. The good performance, wide stable margin and heavy robustness of the valve controller proved that it is a great practical application to enhance the stability of power system.
