Variable Structure and Variable Parameter Control for Hydroelectric Generating Unit

本文阐述了水轮机变结构变参数调速控制的基本问题,提出了相应的控制策略,并论证该控制策略的稳定性、最优性。仿真结果表明本文提出的策略控制效果优良。

The control strategy with variable structure and variable parameter is proposed to cope with the necessity for the governing system of a hydroelectric generating unit to be variable during operation.A variable structure control strategy is developed in connection with the variable plant structure and output variation and a nonlinear compensation approach is proposed and discussed. In addition, for a given plant structure with variable parameters, a time varying parameter control approach is developed and its stability and optimality analyzed. Simulation results show the control strategy proposed is useful for controlling hydroelectric generator sets.
