摘要： A time-based control system (10) for controlling a process incorporating external devices using a predefined response profile (13). The response profile (13) is continuously compared to the actual response of the controlled device (11). A plurality of sensor modules (24) is used to monitor the actual magnitude and direction of change of selected quantities during the process. If the response it outside the user-defined maximum allowable error, appropriate measures are taken to either correct the error, halt the process, or proceed with the process in a time-based mode. The proper response and detection of errors of the controlled device (11) is independent of load, rate, temperature and other external stimuli. The time-based control system (10) can detect errors caused by higher level equipment such as the sensor modules (24). Thus, the time-based control system (10) can detect when any portion of the time-based control system (10) or the controlled device (11) malfunctions. By controlling the controlled device (11) using the time-based control system (10) of the present invention, the present invention is not subject to oscillations, overshoot, or undershoot during the selected process. Therefore, the present invention protects from overload, stuck devices, overheating, and the like without the use of additional sensors.
