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 primary energy source for the controller in a typical control system is usually electrical.
Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.
a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or setpoint, and provides an output to a control element. The controller is one part of the entire control system. these are found in the interior climate control system, and in engine cooling system.

A compensator is a controller meant to improve characteristics of the open-loop plant so that it can safely be used with feedback control. For example, there is a (parasitic) feedback system in a commercial audio system (e.g., in a theater) formed from a microphone, the soundboard connected to it, and the speakers in the theater connected to the soundboard. If the microphone is positioned in certain locations near the speakers and there is enough gain in the system, a single tone (and possibly its higher harmonics) can be reinforced by the feedback system causing it to grow and grow until it is deafeningly loud. It is then the sound engineers' job to "compensate" this system at the soundboard by adjusting the system's gain and phase characteristics around that particular frequency. So here, the soundboard is certainly a controller (compensation is a control topic), but the controller is not responsible for tracking or regulation. Instead, it is enforcing stability of the closed-loop system at all frequencies.
A programmable automation controller (PAC) is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC). Therefore, the PAC features not only reliability as a PLC but flexibility and power as a PC at the same time. PACs are most often used in industrial settings for process control, data acquisition, remote equipment monitoring, machine vision, and motion control. Additionally, because they function and communicate over popular network interface protocols like TCP/IP, OLE for process control (OPC) and SMTP, PACs are able to transfer data from the machines they control to other machines and components in a networked control system or to application software and databases.
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.
