Dynamic Behavior and Stability of Closed-Loop Control Systems
sites.chemengr.ucsb.edu2. The flow-head relation is linear, q3 = h/R. 3. The level transmitter, I/P transducer, and control valve have negligible dynamics. 4. An electronic controller with input and output in % is used (full scale = 100%). The transient responses can be determined in a straightforward manner if the closed-loop transfer functions are available.
