- Human-aided control system for controlling a fluid level in a tank is shown in Figure Q2a. Here H denotes the fluid level inside the tank in meter and Qout be the outflow rate of the fluid from the tank and Qin be the inflow rate of the fluid into the tank. Construct the functional block diagram and identify the controlled variable, controller, actuator, process/plant and measurement element. H Qout ValveWhich claim is correct? A transfer function model for a stable process always has no time-delay. Feedforward control can be solely used for the setpoint tracking If a process has 3 inputs and 3 outputs, then we need to build 6 transfer function models for it. The inner loop of cascade control has to be slower than the outer loop No correct answerNINeveh Digital Techniques University H.W 2:Design 4:16 Decoder from 2: 4 Decoder with truth table ,Boolean Functions and Logic Diagram. ms & Control Engineering Dept.
