MATLAB Online에서 열기 I am getting different results in Matlab & Simulink when I try to simulate step response of a discrete spring mass damper transfer function. Here is my transfer function. H=tf([1],[1 0.2 1]);%transfer function of a continuous system...
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.

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) ...
Convert Discrete-Time Transfer Function to Continuous Time Copy Code Copy Command Create the following discrete-time transfer function: H(z)=z−1z2+z+0.3 Get H = tf([1 -1],[1 1 0.3],0.1); The sample time of the model is Ts=0.1s. Derive a continuous-time, zero-order-hold ...
Yes, I had the same problem.Matlab gives some explanation at "https://nl.mathworks.com/help/simulink/ug/sampletimehiding.html".The workaround by promoting the parameter worked for me. You can read more about promoting the parameter at "https://nl.mathworks.com/help/simulink/ug/param...
This MATLAB function discretizes the continuous-time dynamic system model sysc using zero-order hold on the inputs and a sample time of Ts.
To verify this in the MATLAB environment, type imp = [1 0 0 0 0]; resptf = filter(b,a,imp) respres = filter(r(1),[1 -p(1)],imp)+...filter(r(2),[1 -p(2)],imp) Second-Order Sections (SOS) Any transfer functionH(z) has asecond-order sectionsrepresentation ...
This MATLAB function returns the real numerator and denominator coefficient vectors b and a of the transfer function h.
Transfer function coefficients, specified as row vectors. The transfer function is defined in terms of z–1: H(z)=B(z)A(z)=b(1)+b(2)z−1+⋯+b(n+1)z−na(1)+a(2)z−1+⋯+a(m+1)z−m Example: b = [1 3 3 1]/6 and a = [3 0 1 0]/3 specify a third-or...
