In this paper, we propose an event-driven output feedback control strategy for a class of nonlinear systems subject to disturbances. Different from the time-driven control, the event-driven control can be regarded as a more reactive approach where the control actions are taken only when an event is triggered, thus the event-driven control has a better balance between the control performance and other...
Iterative learning control (ILC) is an effective strategy to deal with repetitive tasks and has been widely applied in industrial systems. Up to now, many control schemes have been proposed to improve the performance of ILC system against iteration-varying disturbances. However, most schemes do not directly utilize disturbance information to attenuate disturbances, which limits the performance of...
In recent years, the trend in large-scale equipment of grinding classification process becomes increasingly common in metallurgical plant. This trend raised the new requirement of much higher efficiency and performance precision in large-scale griding process. Taking into account the peculiarity of strong disturbances and wide operation range in most of domestic concentration plant, several practical...
The standard extended state observer based control (ESOBC) method is only applicable for a class of single-input–single-output essential-integral-chain systems with matched uncertainties. It is noticed that systems with nonintegral-chain form and mismatched uncertainties are more general and widely exist in practical engineering systems, where the standard ESOBC method is no longer available. To this...
