How to speed up simulation time for fuzzy controllers in simulink

18 views (last 30 days)
I have implemented fuzzy controller in simulink as uploaded at http://tinypic.com/view.php?pic=5l9t07&s=6. Fuzzy controller has two inputs with three membership functions and 9 rules.The issue is that; that the simulink is taking too long time to run it. What could be the issue. Any guidance.

You can approximate a nonlinear fuzzy PID controller using a lookup table. By replacing a Fuzzy Logic Controller block with Lookup Table blocks in Simulink, you can deploy a fuzzy controller with simplified generated code and improved execution speed.

You can try running in accelerator or rapid accelerator mode, change to a stiff ode solver or breaking what appears to be an algebraic loop in the feedback with a transfer function or unit delay.

Sir previously sample time was set to -1(inhereted) so when I increased it; the straight line became little curved.The problem is still there..how to solve this problem.Secondly sir can you kindly explain how delay block acts as a sensor and why it is necessary in the model.
