在典型的控制系统中加入迟延环节后，同过simlink仿真后，在小范围内PID和FC控制都有明显的震荡！尤其FC控制较明显，（2）在大范围内PID控制无变化！而FC控制却有很大的震荡。-Typical control system delay link with over simlink simulation, on a small scale the PID and FC control has a significant shock! Especially FC control more apparent, and (2) no change in a wide range of PID control! FC control there is a huge shock.
