Student (Ali) Rollnumber (mcxxxxxx) Solution: CLIPS> (assert (Student (your name))) CLIPS> (assert (Rollnumber (your id )))

Question 2:

You are required to read the research paper on fuzzy system .The paper title is “Autonomous Room Air Cooler Using Fuzzy Logic Control System”. You can also download this paper from the following link.

https://www.ijser.org/paper/Autonomous_Room_Air_Cooler_Using_Fuzzy_Logic_Control_System.html

Tasks:

After reading this paper, you are required to identify the following

a) Fuzzy Input variables

b) Output variables of fuzzy system

c) Ranges

d) Inference rules

e) Short summary of design algorithm

Solution:

a)      “Temperature” and, “Humidity”

b)      linguistic values of fuzzy set(cooler fan speed, water pump and room exhaust fan speed)

c)      “Cold”, “Cool”, “Normal”, “Warm”, “Hot” are used to show the various ranges of input fuzzy variable “TEMPERATURE” , “Dry”, “Not Too Dry”, “Moist”, “Not Too Wet”, “Wet” are used to show the various ranges of input fuzzy variable “HUMIDITY”

MF	Ranges	Regions
Cold	0-10	1
cool	0-20	1-2
normal	10-30	2-3
warm	20-40	3-4
hot	30-40	4

MF	Ranges	Regions
Dry	0-25	1
Not to dry	0-50	1-2
moist	25-75	2-3
Not  to wet	50-100	3-4
wet	75-100	4

d)     R1 = f1 ^ f3 = f1[3] ^ f2[2] = 0.2 ^ 0.4 = 0.2

R2 = f1 ^ f4 = f1 [3] ^ f2 [3] = 0.2 ^ 0.6 = 0.2

R3 = f2 ^ f3 = f1 [4] ^ f2 [2] = 0.8 ^ 0.4 = 0.4

R4 = f2 ^ f4 = f1 [4] ^ f2 [3] = 0.8 ^ 0.6 = 0.6

e)      The simplified design algorithm is used to design the fuzzier, interface engine, rule base and DE fuzzier for the autonomous room air cooling system according to the control strategy of the processing plant to achieve the quality and the quality of the desire needs to maintain the room environment.
