For using fuzzy gain scheduling, we want to find the Kpmin and Kp max, in that, we didn't find and calculate the critical gain and critical period in twin rotor MIMO system.Kindly help me to solve my doubt.

Hi @F. Paul

I assume you want to create a fuzzy logic-based schedule for the proportional gain, ranging from

to

. Are you planning to design a stability-proof schedule with custom-made membership functions, or are you considering following others in creating a heuristic Mamdani FIS schedule using multiple standard membership functions such as trimf and gaussmf?

Could you please provide the mathematical model of the twin rotor MIMO system? Additionally, what are the desired performance requirements for the rotor system?

Regarding the critical gain and critical period, are you attempting to use the Ziegler-Nichols tuning method?
