说明：  实现多种粒子群算法，可对多种方法参数进行优化。希望采纳。(To achieve a variety of particle swarm optimization algorithm, a variety of method parameters can be optimized. Hope to adopt.)

关于matlab的方法及实例，有效，全面，是数学建模的好帮手(about matlab)

关于MATLAB中S函数的编写指导，内容非常详细。(On the preparation of MATLAB S function guide, the content is very detailed)

说明：  利用MATLAB编写GPC预测控制算法程序实现预测控制(GPC predictive control algorithm program written in MATLAB to achieve predictive control)

说明：  在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)
