CR [1] is a promising solution to the problem of spectrum scarcity in wireless communications. The basic idea of CR is to allow secondary (unlicensed) users (SUs) to opportunistically utilize the spectrum of PUs (licensed), provided that the SU transmission do not harmfully affect the PUs. In this paper, we focus on the underlay CR approach, where the SUs access the spectrum occupied by the PUs, given that the interference they cause to the PUs is less than a certain threshold such that the Quality-of-Service (QoS) of the PUs can be ensured

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)
