显示 更早的评论
Hi, How does one specify initial conditions in simulink integrator block for times not t= 0 for example, y(3) =5;

utilize the "External reset" (set as rising) and "Initial ocndition source" (set as external).
Compare clock with t=3 and make it as the "External reset" signal.

Could you give the details of how to "Compare clock with t=3 and make it as the "External reset" signal."
What does "compare clock" mean, and I linked the clock to the "External reset" and the answer has no chage.
A picture on how to set them will be be grateful. Many thanks

Compare Clock with Constant block (value is 3) using the Relational Operator block, the output is trur or false.

Thanks for the prompt reply! I can get the answer for the time after t=3 with the y(3)=5 now. But the problem is for the time earilier than 3 as t<3, is not correct.
I am handling some two point boundary value problem, which y(3)=5 is the end/ final condition. Is there any way to solve this.
It seems can change the initial setting of integrator through properties, but there are no final condition settings.
