- •
We analyze the conditions that produce limit cycle in event based systems.
- •
Then a new tuning method is developed to tune PI controllers to avoid the limit cycles.
- •
Because the method is based on the Describing Function, the effect of higher order harmonics has been studied.
- •
The feasibility of the tuning method is corroborated by symulations and experiments.
