Problem Statement 1

Aim : To devise the control logic of washing machine in Simulink.

Objective : 

• If the power supply is available, the system gets activated. 
• If the Water supply is not available, stop the process & indicate through LED.
• Soaking time should be 200s followed by Washing time of 100s.
• Then rinsing happens for next 20s & dryer runs for 50s.

Problem Statement 2

Aim : To make the gear shift logic with varying speed in Simulink

Objective : 

Make a Simulink chart for the “Gear shift” logic as per below conditions:

        Speed Range(kmph)        Gear 

              0 to 15                         1

             16 to 25                        2

             26 to 40                        3

             41 to 60                        4

             Above 61                       5
