For the liquid-level control system in Figure determine the numerical values of K c and 1
Question:
For the liquid-level control system in Figure determine the numerical values of Kc and τ1; that result in a stable closed—loop system. The level transmitter has negligible dynamics, while the control valve has a time constant of 10s. The following numerical values are available:
Transcribed Image Text:
A = 3 ft? q3 = 10 gal/min K, = -1.3 gal/min/mA Km (for control valve) 4 mA/ft (for level transmitter)
