conical tank level control fuzzy

[ajay_amar]

respected sir,

As we are planning to control the level of a conical tank using fuzzy logic. We just need to know how to start the project we are confused where to start first. Kindly tell us where to start with.

regards,

A.Ajay

Based on volume? Pressure? Level?  Percent Full?

sir, i am doing a project on level control of a conical tank using PID control and adaptive neuro technique. but i have certain problems in LabVIEW regarding the open loop response based on the mathematical model that i have derived.I did not get a dead time for my curve.since that is the 1st step for simulation,i am stuck and i want your help.

# i want to control the level(dh/dt) of the tank.

# the mathematical model is

                      dh/dt= fin - (cv*sqrt(h)) /  ((pi*R^2*h^2)/H^2)

h- level of tank at any point of time(m)

H-height of the tank(m)

fin-inlet flow(m^3/sec)

fout-outflow, fout=cv*sqrt(h)(m^3/sec)

cv-valve coefficient

R-radius of tank at height H(m)

# it would be helpful if you sent me a LabVIEW program based on this.

# i hav attached mine.
