First, input a sine signal into the nonlinear system to obtain a set of input-output data, train a neural network, and then use this neural network to predict the output of the nonlinear system. %shenjingwangluoxunlian close all clear ; y_1=0; y_2=0; z_1=0; z_2=0; t1=0:0.05:50; u1=10*sin(2*pi*5*t1); Len=length(u1); yy1=zeros(1,Len); for k1=1:Len z_0=u1(k1); y_0=0.2*y_1/(1.5+0.1*y_1*y_1)-0.4*y_2-0.8*z_1+0.6*z_1*z_2; yy1(k1)=y_0; y_2=y_1; y_1=y_0; z_2=z_1; … Read more
Have you ever wondered how micro-robots smaller than a coin can move as flexibly as Transformers? The answer lies in their “heart”—the actuator. Recently, Professor Zhang Yihui’s research group from Tsinghua University’s School of Aerospace Engineering and the National Key Laboratory of Flexible Electronics Technology has developed the world’s smallest and lightest micro wireless amphibious … Read more
