WebJun 7, 2024 · It takes 100 steps to finish the 0 to 5 second simulation. If the solver and stepsize have to be something else, then put the MATLAB Function block inside a triggered subsystme, Use a Function Call Generator block to trig the subsystem, set the "sample time" of the Function Call Generator to be 0.5. WebWhen the fundamental sample time is set to auto the following occurs: 2.If the model does not define any periodic sample times (it only contains continuous states), Matlab chooses a step size that divides the total simulation into 50 equal steps (if the simulation is set to run Inf, this time is 0.2). WebSet point tracking performance is then explored as a function of control loop sample time, T. • Step 1: Establish the Design Level of Operation (DLO) We arbitrarily initialize CO, PV, SP and D all at 50% and choose this as the default DLO. • Step 2: Collect CO to PV bump test data around the DLO how can we stay in shape
