Closed loop MBI system
Short answer
A closed-loop microprocessor-based system feeds back the measured output through a sensor and ADC, compares it with the set value, and adjusts the actuator via DAC or output port to maintain the desired condition. For example, an oven temperature controller switches the heater based on sensed temperature to hold 200°C.
What do you understand by a closed loop MBI system?
A closed loop MBI system is a microprocessor based system in which the output (controlled variable) is continuously measured by a sensor, converted to digital form by an ADC and fed back to the microprocessor. The microprocessor compares it with the set value, computes the error, and drives the actuator through a DAC or output port so that the error becomes minimum. Example: a microprocessor controlled oven that keeps temperature at 200 deg C by switching the heater according to the sensed temperature.
