Abstract: A method includes a step of obtaining in a processing circuit a sequence of elements between a first device and a supply air temperature sensor of an air handling unit. The processing circuit also obtains an estimate for time constants associated with each element of the sequence. The processing circuit adds the time constants to obtain a process time constant estimate. The method further includes controlling a device based at least in part on the process time constant estimate.

Abstract: An apparatus and method is disclosed for automatically controlling multi-input-single-output (MISO) systems or processes. The control output signal of a single-input-single-output (SISO) automatic controller is converted by a reverse, sequential or combined split-range setter into a plurality of ranges of signals so that the SISO controller is converted to a single-input-multi-output (SIMO) automatic controller based on certain criteria; and the resulting controller output signals are able to manipulate a plurality of actuators to control one continuous process variable in different operating conditions. Without the need of building process mathematical models, this inventive apparatus and method is useful for automatically controlling unevenly paired multivariable systems or processes where there are more system inputs than outputs including but not limited to pH processes, chemical reactors, and air handling units.
