In most instances, feedback control meets the objectives for both aeration limitation and containment of effluent ammonia peaks. Feedforward control, applied specifically for switching aeration on or ...

When there exists strong noise factors in the process, robust parameter design alone may not be effective, and a control strategy can be used to compensate for the effect of noise. In this article a ...

Eventually, multivariable, model-predictive control replaced simpler APC approaches and algorithms for both feedforward and feedback control of complex process control applications. But, throughout ...

Scientists in Saudi Arabia have created a PV-powered air water generator that can be used in remote areas or on lengthy vehicle journeys. It can reportedly produce a liter of water at approximately $0 ...
