capon波束形成算法，经典的波束形成算法，能有效形成波束(Capon beamforming algorithm, the classic beam forming algorithm, can effectively form the beam)

一个用simulink做的模糊PID自适应系统，FIS等都比较简单，适合初学者。通过与PID的比较曲线可以看出此系统更加优越。(A simulink do with self-adaptive fuzzy PID system, FIS are relatively simple, suitable for beginners. Comparison with the PID system curve can be seen even more superior.)
