Water level and Water flow process control (ref: ERD551000)
ERD551000:
Module for the study of Water level and Water flow process contrl, with 1 column, and with a pure delay. The level and flow sensors are of industrial type and are directly interfaced in a 4/20-mA current loop.
Exists also with 2 columns (ref ERD552000)
2 versions are available :
– Water level and water flow process control with 1 column (ref ERD551000) (here)
– Water level and water flow process control with 2 columns (ref ERD552000)
Topics:
Study of the characteristics of level and flow sensors
Identification in open loop of a level and flow process
Control with digital PID, ON/OFF correctors, fuzzy logic, Z transfrom of :
– Water flow
– Water level of 1st or 2nd order, with or without pure delay.
Program functions :
Selection of the system structure : open loop, closed loop for water flow, for water level.
Selection of the control type and specific values: constant step, ramp, sine, trapezoid signals.
Selection of the corrector: P/PD/PI/PID ; On/Off ; Digital; cascade control
Optional extra:
ERD550800, D_Scil : Module for prototyping with Scilab/XCOS, creation of correctors, real time, implementation in the control and acquisition module.
