Consider a proportional controller whose transfer function is 15 and its reference value is 50% of output. Its output signal goes to a valve whose reference value allows a flow of 200 m/s. The valve modifies its output by 4 m/, for each percentage unit change in controller output. What will be the controller output and deviation in error if it is necessary to change the flow to 240 m/,?

Example 1.1 Figure 1.5 shows the block diagram of a closed-loop flow control system. Identify the following elements: (a) the sensor, (b) the transducer, (c) the actuator, (d) the transmitter, (e) the controller, (f) the manipulated variable, and (g) the measured variable. In the figure above, the (a) sensor is labeled as the pressure cell. The (b) transducer is labeled as the converter. However, there are two converters: one for converting pressure to current, and another converting current to pressure for operating the actuator. The (c) actuator is labeled as the pneumatic valve. The (d) transmitter is labeled as the line driver. The (e) controller is labeled as the PLC. The (f) manipulated variable is labeled as the pressure developed by the fluid flowing through the orifice plate. The (g) measured variable is the flow rate of the liquid.
In the mid-1900s, several technological and analysis concepts came together to make the PID controller widely accepted as an effective industrial controller. Discuss in detail and evaluate the performance of a PID or three-term controllers that are widely used in a typical paper mill where there may be about 2000 control loops, and over 90% of these would be PID control loops.
A proportional controller is used to control the height of water in a tank where the water level can vary from 0 to 4.0 m. The required height of water is and the controller is to close a valve fully when the water rises to 3.9 and open it fully when the water falls to 3.1 m. What transfer function will be required? source : Mechatronics: Electronic Control Systems in Mechanical and Electrical Engineering 6th Edition by W. Bolton question 22.4

A control valve is used to manipulate a liquid flowrate in the flowrate control loop. Figure 2 shows the flow characteristic of the control valve.Determine the following: i. Type of flow characteristic of the control valve.ii. Flowrate through the valve if the valve travel is 45%. Noted that the flowrate of the liquid is 70 000 lb/h when the valve is fully opened.iii. The maximum flow coefficient of the control valve, if the density of the liquid is half of the density of water and the pressure drop across the valve is 10 psi.
