Plantwide control design for the economically optimum operation of the power demand control system and applied to an iron and steel plant, which is consisted of a supervisory control layer on top for ensuring feasibility and economically optimal operation and several regulatory control units that ensure safe and stable operation. The supervisory layer has two main tasks. First, there is a supervisory...
By using finite-element analysis theory, we divided wheat into a finite number of units and assumed the displacement of joint between units as unknown, building the lodging-resistant mechanical model of wheat. Combining with the model analysis method, we calculated steady state response caused by harmonic load excitation and analyzed the maximum displacement of wheat spike at certain wind scale, thereby...
This paper utilized multi-degree of freedom vibration theory combined with considering the influence of synergy of wind load and self-weight on the wheat to build the five-degree of freedom mechanical model of wheat and calculated the lodging bending moment of wheat root under a certain wind scale, in response to lodging problem in the late period of wheat development. Because of the complicated distribution...
