First, write out the four matrices of the state-space model for the two systems separately, then call feedback() to establish the feedback connection, and finally call step() to test the step response curve of the overall system. %% Feedback connection between two state-space systems %% feedback(); %% step(); %%%%%%%%%%% clear all; clc; close all; %%%%%%%%%%%%% … Read more
First, use MATLAB to draw the system signal transfer block diagram, then extract the transfer function from the block diagram, and finally plot the system’s step response curve. clear ;[a1, b1, c1, d1]=linmod(‘ex202501’);ss1=ss(a1, b1, c1, d1);tf1=tf(ss1);figure(1);step(tf1);grid on;hold on;num1=tf1.num{1};den1=tf1.den{1};t1=0:0.01:25;x2=20.0*sin(2.0*pi*3*t1);y2=lsim(num1,den1,x2,t1);plot(t1,y2);
First, input the coefficients of the numerator and denominator polynomials of the closed-loop transfer function, and then use the step function to plot the response curve.
