| Abstract: | The principle of exact linearization is presented and the computer algebra design method for the exact linearization of state feedback in nonlinear control system is discussed.The corresponding software package is developed with Matlab and applied in the nonlinear control of steam valve in steam turbine generator set of power system for simulative analysis.Simulative result shows that the system stability is effectively improved after the nonlinear control variable is imported.This project is supported by the National Natural Science Fund of China(60343002). |
