a design methodology is introduced that blends the classical PID and the fuzzy controllers in an intelligent way and thus a new intelligent hybrid controller has been achieved. Basically, in this design methodology, the classical PID and fuzzy controller have been combined by a blending mechanism that depends on a certain function of actuating error. Moreover, an intelligent switching scheme is induced on the blending mechanism that makes a decision upon the priority of the two controller parts namely, the classical PID and the fuzzy constituents. The simulations done on various processes using the new hybrid fuzzy PID controller provides ‘better’ system responses in terms of transient and steady-state performances when compared to the pure classical PID or the pure fuzzy controller applications. The controller parameters are all tuned by the aid of genetic search algorithm.

使用matlab语言实现的时域有限差分算法(finite differentiate time domain)

说明：  用于波束成形的matlab代码，主要思想是用DFT码本实现(A large number of antennas are arranged at the base station of the system, and then the signals from different directions are weighted by beamforming preprocessing. After that, the power of each signal can be concentrated in a certain beam space for transmission,)
