This allows the controller to continue effectively controlling the system after an equipment malfunction. In a simpler control, such as PID control, this would not be possible. MPC is a highly specific method for controlling a process.

By providing a closed loop controller that measures the terminal voltage w.r.t. a desired value, the terminal voltage can be maintained across the load range simply by varying the rotor's excitation field strength.

    A systemic approach to storage tank overfill protection

    Automatic shutoff. The system controlling filling operations must also have effective alarms combined with automated shutoff. When using a manual filling procedure, operators must be made aware when a high level threshold has been crossed while there is still plenty of time to take corrective action before an automated shutoff system intervenes, which will likely cause some disruptions.[tank]Waterman Valve LLC Control Gates for Municipal Water [steel]Corporate Office 25500 Road 204 Exeter, California 93221 Office(559) 562 4000 Fax(559) 562 2277[tank]Farm scale ethanol fuel production plant[steel]Farm scale ethanol fuel production plant Design Report By controlling the rate of water flow through this exchanger, the temperature of the alcohol entering the reflux drum can be maintained at a constant.
