1.0 OBJECTIVE OF AUTOMATIC PROCESS CONTROL

      Process control is needed because various disturbances disrupt a process’s efficiency. Such disturbances include both known and unknown inputs and conditions (e.g., changing flows, chemical and biological compositions, temperature, and density). Process control devices (e.g., valves, flow meters, pumps, and other
