A servo control loop is one which responds to a change in setpoint. The setpoint may be changed as a function of time (typical of this are batch processes), and therefore the controlled variable must follow the setpoint.
and,
A regulatory control loop is one which responds to a change in some input value, bringing the system back to steady state. Regulatory control is by far more common than servo control in the process industries.
When setpoint is changed and PV moves to SP, this is servo controls. When the disturnbances are rejected by the control system , then it is regulatory controls.

Difference between control process and process control is that system control process is typically the large scale version of where process control is used.
The controls are seperated
different between the order and the type of control system eith examlpe

The difference between the type of government and the system of government is the way in which they act for the people. There are only two forms of government, those that are controlled by the people and those that control the people.
SCADA will perform supervisory action over Distributed control system to make sure that every thing is working fine.
Heart rate is controlled by the cardiovascular -regulatory systme which is part of the autonomic nerve system.
The endocrine and nervous systems control the endocrine system. Messages from these systems cause the endocrine glands to change their production of hormones.
Hormone levels can be controlled by the nervous system (neural control), by other hormones (hormonal control), or by body fluids such as the blood (humoral control).
MCC-Motor control center which consist of motor staters to control the motor. PCC-power contol center which is control the power to distribution system
The main difference between ADODC and ADODB is that whereas ADODB is a class library, ADODC is just but a data control. The other difference is that ADODC uses the system resources more compared to the ADODB.
