数字滤波是将输入的信号序列，按规定的算法进行处理，从而得到所期望的输出序列。(Digital filter is the input signal sequence, the algorithms for processing by the regulation, and the desired output sequence is obtained.)

Calculate the lyapunov index toolbox. Contains a variety of methods, can be directly run.

第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)
