discrete controller Ts problem
显示 更早的评论
hello good day everyone, i am quite new to simulink and currently i am creating an induction motor and controlling its speed for a project in school(simulation of an electric vehicle). I am having a wierd problem, i was able to get it working last night, i was able to set the speed and from the output you could see the controller was working, however in the morning i keep getting an error, Undefined function or variable 'Ts'. I have tried using a simout and constant to declare this variable. i'm a bit new. Any help would be greatly appreciated.Thank you in advance.

So this Ts is actually in the DTC block of your model. Go to Explorer(by right clicking onto the DTC block). Then go to Unit Delay1, there you can see the time period defined as Ts. You need to change it there. Define some value. I am afraid I can't help you more than that as this is not my subject. Hope it helps.

By the way Ts usually refers to sampling time. So maybe that can help you.

Hi Navin, i am simulating power electronics problems and i use powergui in discrete mode. when i am trying to use Ts as symbolic sample time in some blocks (e.g. Switch, ...), i face an error "Ts is undefined function or parameter". I appreciate if you can advice me how to solve this matter.
