Fuzzy Control of a Multivariable Nonlinear Process
نویسندگان
چکیده
This paper presents a qualitative control of a fluid mixer, which is a multivariable and intrinsically non-linear plant. The mixer has as inputs two fluids of different colours and the output is the colour of the resulting mix. The control system consists of two independent fuzzy controllers which are responsible for maintaining the water level at a given height and for adjusting the colour of the fluid in the mixing tank. The main points studied are the response when the desired colour is changed and when the output flow changes. Simulation results show that the approach of using two independent controllers, with simple rule-bases, can give good results.
