Penicillium crystallization process control based on fuzzy controller with nonlinear scaling factors

Crystallization process control system is a complex system with time variable parameters. Temperature rising rate requirement in each running stage is deferent. In this paper it is introduced a nonlinear scaling factors fuzzy control scheme, which can tune and optimize the parameters of scaling factors based on genetic algorithm(GA). From the simulation result, it shows that control system has the character of good performance and strong robustness.
