Static and dynamic graphs modeling of a boiler system / Noor Ainy Harish

Fuzzy State Space Model (FSSM) is a novel inverse modeling technique used for optimization of input parameters in multivariable dynamic systems whereby the uncertainty of the parameters is considered and incorporated with the crisp state space models proposed in the modem control theory. The model...
