“…In most industrial process control applications, the inherent (gradual) time-varying nature of the plant dynamics diminishes the lifetime performance of model-based control systems (see MacGregor & Cinar, 2012;Qin, 2012;Yin, Ding, Haghani, Hao, & Zhang, 2012;Shardt et al, 2012 for recent reviews on performance monitoring and diagnosis). Changes in the plant dynamics over time increase the plant-model mismatch, which may eventually invalidate the model identified at the commissioning stage of a model-based control system.…”
