Q5. Fuzzy Logic and PLC Ladder Diagram

a) Develop a fuzzy inference system for grading a robotics course. The inputs are your effort level(low and high) in the course and your test grade (poor, moderate, and good.) The output is your letter grade (A, B, C,D and F). Write the rule base for the system.

b) Two different motors need to be controlled using a Programmable Logic Controller (PLC). A push button switch turns on the first motor. This Motor needs to be turned off after 60 seconds using a timer. 60 seconds after the first motor turns off, a second motor needs to be turned on. This motor needs to be turned off after 120 seconds using a timer.

Draw the ladder diagram to implement this control sequence.
