Sample time: 1 seconds Discrete-time transfer function. 例2 clear all; clc z=tf('z',1); sys=(z^2+2*z+3)/(5*z^2+6*z+7) 结果为: sys = z^2 + 2 z + 3 --- 5 z^2 + 6 z + 7 Sample time: 1 seconds Discrete-time transfer function. 2.离散状态方程模型 离散状态方程的...
Create Discrete-Time Transfer Function Model This example shows how to create a discrete-time transfer function model usingtf. Create the transfer functionG(z)=zz2−2z−6with a sample time of 0.1 s. num = [1 0]; den = [1 -2 -6]; Ts = 0.1; G = tf(num,den,Ts) ...
Estimate a discrete-time transfer function with two poles and one zero. Specify the sample time Ts as 0.1 seconds and the transport delay iodelay as 2 seconds. Get np = 2; nz = 1; iodelay = 2; Ts = 0.1; sysd = tfest(umat2,ymat2,np,nz,iodelay,'Ts',Ts) sysd = From inp...
Create the discrete-time transfer function model. Get numerator = [2,0]; denominator = [4,0,3,-1]; ts = 0.1; sys = tf(numerator,denominator,ts) sys = 2 z --- 4 z^3 + 3 z - 1 Sample time: 0.1 seconds Discrete-time transfer function. Second-Order Transfer Function from...
Use filt to create discrete-time transfer function models in digital signal processing (DSP) form for use with Control System Toolbox linear analysis and control design tools.
Discrete-time transfer function. 其中,c2d函数的用法,应该是离散化。(其中ts=0.001;) 离散时间传递函数 创建MATLAB的工作目录:(插入图片太麻烦,略) 然后新建 (左上角) Clear是清除变量,clc是清屏 方法一:选中要屏蔽的程序,然后按Ctrl + R; 方法二:在要屏蔽的程序前加上符号% ...
Sample time: 0.1 seconds Discrete-time transfer function. In this example, the discretized modelhdhas a delay of three sampling periods. The discretization algorithm absorbs the residual half-period delay into the coefficients ofhd. Compare the step responses of the continuous-time and discretized mo...
ans = z - 1 --- z^2 + z + 0.3 Sample time: 0.1 seconds Discrete-time transfer function. Use the Tustin approximation method to convertHto a continuous time model. Hc2 = d2c(H,'tustin'); Discretize the resulting model, Hc2, to get back the original discrete-time model,H. c2d(Hc2...
Discrete-time model. 2. 脉冲传递函数描述法 脉冲传递函数也可以用tf命令实现。 语法: G=tf(num,den,Ts) %由分子分母得出脉冲传递函数 说明:Ts为采样周期,为标量,当采样周期未指明可以用-1表示,自变量用'z'表示。 【例6.2续】创建离散系统脉冲传递函数 num1=[0.5 0]; den=[1 -1.5 0.5]; G1=tf(nu...
