摘　　要：抽水蓄能电站的可逆式机组具有强非线性与工况复杂性特点,采用理论或试验的方法均难以得到其动态特性的精确表达。在建立可逆式机组不确定参数模型的基础上,通过构造控制系统输出函数和上界函数,研究了基于滑模结构的鲁棒控制策略。理论推导与仿真试验表明,所研究的控制策略具有对运行工况变化适应性强和应用方便的特点,是解决可逆式机组复杂非线性控制问题的一种有效方法。Due to the strong nonlinear characteristics and the operating conditions complexity of pump turbine of the pumped storage power station,it is unable to get the accurate dynamic characteristic expression from the method of theory research and model test.Based on the establishment of uncertain parameters model of reversible units,we have studied the robust control strategy based sliding structure by constructing a control system output function and the upper bound function.Theoretical analysis and simulation test results show that the robust control strategies can well adapt to the changes in working conditions and is easy to be applied.Thus,it is an effective way to solve complex nonlinear control problems of the reversible turbine.
