(PID solution with the requirements and simple explanation. Thx) INSTRUCTION: Given three bare processes develop a control system using feedbackand feedforward concept/principle. Your output is a process and instrumentationdiagram (P & ID) using ISA's Instrument Identification and Symbols standards withexplanation. PROCESS 2: The liquid level inside the tank is regulated at a value of 3.0 m on a condition ofcontinuous liquid inflow and outflow. Requirements: Two feedback solutions One feedforward solution
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 Valve
1. Give an example of open loop and closed loop system (one example each). Also state the input, control system, feedback and output parameter. Example. 1. Open Loop - Water Heater: Input - Water Temperature (Cold) System - Heating Element Output - Water Temperature (Hot) 2. Closed Loop - Air-conditioning System Input - Desired Room Temperature Control - Motor controller/Compressor/ACU Feedback - Temperature Sensing Output - Room Temperature
b) Consider the evaporator which concentrated the salt solution and the transfer functions of all open systems are first-order system. 1) Design the cascade control loop and block diagram. If the evaporator temperature and steam flowrate of coil are controllerd variables and if the inlet concentration and presure of coil steam are disurbance variables.
Identify the following elements of the given closed loop control system.(i) Process Element(ii) Feedback Element (iii) Control Element (iv) Correction Element
Name two effects of negative feedback.
The governor is a mechanically-controlled feedback device which maintains the speed of an engine within permissible range whenever there is a variation of load. There is various type of governor in the industry as shown in Q6(a). With the aid of a diagram of forces acting on the governor at the equilibrium, explain the limitations of a Watt governor and how these are rectified in the Porter governor. Figure Q6(a): Various types of governor.
One of the disadvantage of negative feedback loop is lag caused because it can only be exerted after controlled variable has been disturbed. In order to minimize lag between a change in a controlled variable and the action of the effector, it is advantageous for the body to anticipate any likely change. Which one of the following physiological mechanism achieves this? Select one: a. Feedbackward control b. Feedforward control c.Positive feedback control d. All of the above e. None of the above

In an industry, the water in a boiler tank needs to be kept at constant pressure, water to the tank comes at constant flow rate and steam is coming from a valve to maintain the pressure. A pressure gauge is used to measure the water pressure in the tank. a. Provide the block diagram representation using a PID controller for the above mentioned condition (Control the pressure using the proportional valve.). b. explain the working principle.
