Question

Using a specific control system as an example (position control, temperature control, pressure control, flow control, etc.), describe how you would apply the four design steps to meet the design criteria.

Note: please type the answer

Answer 1

here we are taken an example that temperature control system

1. temperature control system:

• we should take a case of a temperature control framework in which 50 degre centigrade is the reference temperature set
• give the plant a chance to be a stove of sensor appended to the plant.
• let a thermocouple as appended to the plant as a sensor .
• from the attributes of the sensor , we know how much voltage is delivered over the terminals of a thermocoples at a specific temperature .
• let the specific temperature is created by thermocople produces 50mv to 50 degree centigrade.

circuit diagram of temperature control system:

• 
• these figure here is a case of the reference setting,by varreying the opposition the yield voltage varried .
• there fore temperature as altered as voltage here 50 dgree cencentigrade compares to 5voltage

the thermocouple which can produce voltage in mv range,its convert in volts by using amplifier:

the thermocouple output is smplified:

NOW working:

• at the point when the reference is 50 centigrade .set the reference voltage as 50V.
• at 50 dgree centigrade thermocouple create 50MV
• presently it the stove temperature additionally increment the comparator yield is 0.the yield of comparator is nourished to a switch of water.
• which influences the warmer off the raising temperature to case

• presently soon as the temprature falls the thermocouple yield will be decrese.when it falls beneath 50MV,voltage reference will be more prominent than the opened up voltage of thermocouple ,
• the yield of the comparator will be 1.this does the radiator switch ON and temparature rises
• this procedure keeps on making a control temperature framework.
