The design employs feedback linearization, coupled with two high-gain observers: the first to estimate the feedback linearization error based on the full state information and the second to estimate the unmeasured states of the system when only the system output is available for feedback. All the signals in the closed loop are guaranteed to be uniformly ultimately bounded(UUB) and the output of the system is proven to converge to a small neighborhood of the origin. The proposed approach not only handles the difficulty in controlling non-affine nonlinear systems but also simplifies the stability analysis of the closed loop due to its linear control structure. Simulation results show the effectiveness of the approach.展开更多

The Internet of things technology has shown significant superiority in solving that＇s problem because of its traceability characteristics, dynamic. This paper takes the Internet of things technology as the basis, starting from the end of the collection, transportation and treatment of urban wastes in three aspects, construct a closed loop waste treatment system has good information feedback and processing capacity.展开更多
