| Popis: | The boiler-turbine process of the thermal power system is a typical multi-input-multi-output system. There is a strong coupling among the control loops and the process exhibits strong nonlinearities, conventional control strategies cannot achieve satisfactory control performance and meet production demands. The dynamic characteristics of the boiler-turbine systems are further researched in this paper and the globally linearizing input-output feedback linearization control technology is applied. The control method can not only reduce the effects of the nonlinearities on the system but also eliminate the coupling among control loops. Simulation results show that the globally input-output feedback linearization control technology has a better control quality and can improve the control performance compare of conventional feedback linearization method. |
