Application Of New Control Strategy To Main Steam Temperature Control

The control system is a important component in the power plant and the object of system with characteristics of nonlinear, time-variant and etc has large inertia , large delay and many disturbances. Especially, the object became much complicated and demanded much better control to the system. So The conventional superheated steam temperature cascade de-temperature control system cannot satisfy the demand already. The system process was modeled and an inverse model controller using support vector machine regression(SVMR) was designed. First, the SVMR principle was briefly introduced. Second, the SVMR was applied to the internal model control(IMC) problem, and the SVMR internal model was developed. Third, an SVMR controller for internal model control problem was proposed under the inverse condition of control process. The controller was applied to the control of superheated steam. Finally, the simulation improved the validity to the control of superheated steam temperature.Wang Lei (Thermal power engineering) Directed by prof. Gu Junjie...
