Thank you for your reply.
With the Gaussian distribution as input, fuzzy logic controller can manage better the noise in the input data.
You can check this paper for some details: “A. Pourabdollah, C. Wagner and J. Aladi, Changes under the hood – a new type of non-singleton fuzzy logic system”. Currently, we are writing a paper where we control UAV’s position with singleton and non-singleton fuzzy logic controllers.
