用二维热传导分数步长法求解二维热传导方程，其中解转化来的方程用的是追赶法,分别用了ADI,LOD,对称LOD方法进行求解(Solving the two-dimensional heat conduction equation with two-dimensional heat conduction fractional step method, Solving the two-dimensional heat conduction equation with two-dimensional heat conduction fractional step method, which transformed to the equation solution is to catch up with the law, respectively, with the ADI, LOD, LOD method for solving symmetric)

了等距线阵方向图与傅立叶变换的一致性，用F丌算法进行阵列方向图快速计算。通过严格的数学推导，揭示变换序列与可见空问的关系，讨论了不同单元问距情况下的处理方法(In this paper，the consistence of equispaced linear array pattem and foureir transfom is analyzed，so the linear arrayy pattem can be computed rapidly with FFT a1goritllm．By the use of reUgious mathmatic deducing process，relation between transfotmation sequences and visible space are given，and different handling procedures are discussed in the case of different element spacing． )

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)

阶跃相应绘图，可以调整波形，画出bode图(Step the corresponding drawings, waveforms can be adjusted, to draw bode diagram)
