Question

In the circuit below, the PIC microcontroller is used to receive serial data using the RS-232 protocol on RA0 and display it on the LEDs attached to PORTB. The microcontroller performs this operation every time the button attached to RA2 is pressed and released.

Assume you have a fuzzy logic controller for "Liquid Level Controlling". Two inputs are defined for the Fuzzy Controller. One is the level of the water in the tank denoted as Level" and the other one is rate of change of water in the tank denoted as "Rate. The controller task is to govern the opening of the valve which is the output of the controller and is denoted by "Valve" What would be the "Valve control value if the "Level" is 35 feet and the "Rate" is -0.3 when you have the following rules and fuzzy membership functions? Rules: If Level is Low and Rate is Negative then Valve is Open If Level is Normal and Rate is Zero then Valve is No Change If Rate is Not Negative then Valve is Closed
