单元机组协调控制的一种频域设计方法

A Frequency Domin Method for the Design of Coordinated Control System of a Unit Power Plant

本文研究了主导增益法在单元机组协调控制系统设计中的应用,并在所设计的鲁棒控制器基础上提出了一种变参数控制方案。仿真结果表明鲁棒控制器能满足变负荷运行要求,而变参数控制器明显地改善了系统的性能。

This paper considers the application of principal gain method to the design of coordinated control of a once-through boiler-turbine unit. Based on the robust controller designed by PG method, a simple parameter-varying controller is presented. The simulation results show that the robust controller can fulfill all the operational requirements and that the parameter-varying controller improves the system performance remarkably.
