模糊滑模控制的例子，应用于自动控制领域。(Fuzzy sliding mode control for example, be applied to the field of automatic control.)

说明：  负荷频率控制（LFC）是调整系统的频率达到额定值（如50HZ）或/和维持区域联络线交换功率为计划值。频率稳定是电力系统电能质量的一个重要指标。负荷的任意突然变化都有可能导致系统间联络线交换功率的偏差及系统频率的波动。因此，为保证电能质量，需要一个负荷频率控制(load frequency control,LFC)系统，该系统的目的是将系统频率维持在标称值并且尽可能使控制区域之间的未计划的联络线交换功率最小。(Load frequency control (LFC) is to adjust the frequency of the system to reach the rated value (such as 50 Hz) or / and maintain the exchange power of the regional tie line to the planned value. Frequency stability is an important index of power quality in power system. Any sudden change of load may lead to the deviation of power exchange between tie lines and the fluctuation of system frequency. Therefore, in order to ensure the power quality, a load frequency control (LFC) system is needed. The purpose of the system is to maintain the system frequency at the nominal value and minimize the unplanned tie line exchange power between the control areas.)
