A PI controller is required for the following control problem:
a. Temperature is to be controlled from 50° to 150°C with a set point of 100°C.
b. A sensor provides temperature-dependent voltage as
V = (T - 100)/10 + 5
c. An 8-bit ADC is used for which 00H is 0 V and FEH to FFH occurs at 10.0 V. d. The PB is 70%, and the integral gain is 1.5 min-1.
e. Sample time is 0.5 min.
f. Output is through an 8-bit DAC with a 10.0-V reference. Develop a flowchart for the control process, control equations, and a program in the language of your choice.
