Abstract

Several dynamic acceptance test approaches, applicable to any linear, causal, time-invariant control system, are developed. The acceptance tests perform a reasonableness check on controller outputs, based upon critical control theory. The dynamic approach checks the control system online and in run-time and reacts to controller demand changes as the control system operates. Theory is presented to enable one to place dynamic magnitude and rate bounds on controller output signals in the time domain. Practical implementation of the acceptance tests into realistic control systems is discussed leading to verification of a highly successful fault detection technique
