Trajectory designing Matlab code
显示 更早的评论
Hi Dear all i want to make a trajectory path which i have done but i am unable to get the output in simulink please help me fast what mistake i am doing????
function [a3,a2,a1,a0]= TrajCreate(theta0,thetaf,thetad0,thetadf,t)
T=20;
a0 = theta0;
a1 = thetad0;
a2 = (-3 * (theta0 - thetaf) - (2 * thetad0+thetadf )*T)/ T ^ 2;
a3 = (2 * (theta0 - thetaf) + (thetad0+thetadf )*T)/ T ^ 3;
end
% Run File theta0=10; thetaf=50; thetad0=0; thetadf=0;
[a3,a2,a1,a0]=TrajCreate(theta0,thetaf,thetad0,thetadf)
p=[a3 ,a2 , a1 , a0];
t=linspace(0,20,100);
Pos=polyval(p,t)
plot(t,Pos)
This give me nice result but i want the Pos my output in simulink
can you some one please help me
thanks in advance

You can use From Workspace block to transfer trajectory signal data from MATLAB base workspace to Simulink.

"I have already done that but unable to get that"
please explain the problem in detail. It is difficult to guess the problem you are facing. Please provide more detail of what is not working and if possible attach a sample model and dataset with your comment.

difficult to guess the problem you are facing !!!!! the way you just answer the question _ _ You can use From Workspace block to transfer trajectory signal data from MATLAB base workspace to Simulink.__ on what basis you said this..... Anyway the problem is simple.... in the Pos variable i have getting a s like curve ,but now my question is i want to use this variable simulink
hope now you get what i am trying to ask

Here is a simple example demonstrating how to use From Workspace to get base workspace data in Simulink.
First, run this code to create sample data:
t = 0:0.1:10;
y = t.^2;
data = [t' y'];
Then run the attached Simulink model. Also check the setting of the From Workspace block to see how to set the variable name.

Right-click on the file name and press Save Link as. Also instead of starting a new answer, it is better to keep comment on the original answer. It helps keep track of the things.
