In order to determine the discrete transfer function of a zero-order hold (ZOH) system in Matlab, it is necessary to begin by defining the continuous transfer function of the system. This can be achieved by utilizing the tf() function to specify the coefficients of the numerator and denominat...
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...
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...

在Estimate选择Transfer Function Models,然后设置合适的零点极点。电机模型一般零点为1极点为2。 由于我们的转速的编码器采集的离散数据,所以我们需要将默认的连续性数据选项改为Discrete-time (Ts = 0.0x)(由于后面仿真的时候节点选的都是连续型,这里也就先按连续型做系统辨识,为了尽量保证准确性等我开学回实验室再...
For discrete-time systems, the state-space matrices relate the state vectorx, the inputu, and the outputythrough x(k+1)y(k)=A x(k)+B u(k)= C x(k)+D u(k). The transfer function is the Z-transform of the system’s impulse response. It can be expressed in ter...
