  • Publication number: 20210087074
    Abstract: A cooperative fuzzy-neural control method is designed in this present invention. Due to the difficulty for cooperatively controlling the concentrations of the dissolved oxygen and nitrate nitrogen in wastewater treatment process, a cooperative fuzzy-neural control method is investigated. In this proposed method, firstly, a interval type-2 fuzzy neural network is employed to construct the cooperative fuzzy-neural controller. Secondly, a parameter cooperative strategy is proposed to cooperatively optimize the global and local parameters of the cooperative fuzzy-neural controller to meet the control requirements. This proposed cooperative fuzzy-neural control method can cooperatively control the concentrations of the dissolved oxygen and nitrate nitrogen in wastewater treatment process. The results illustrate that the proposed cooperative fuzzy-neural control method can achieve the high control accuracy and guarantee the normal operations of wastewater treatment process under the different operation conditions.

  • Publication number: 20210013777
    Abstract: A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.

  • Patent number: 10661900
    Abstract: An apparatus and kit for assembling a mobile platform and methods for making and using the same. When associated with a mobile platform, a power device can be installed outside a control device coupled with the mobile platform. The power device can be located outside a housing enclosing the mobile platform and exposed to an external operating environment of the mobile platform. Heat generated by the power device can be dissipated without installation of additional cooling equipment. The power device and the control device can thus have lower operating temperatures and longer lifetimes. The power device can be installed on a module associated with the mobile platform for further improving heat dissipation of the power device. The module optionally can function as a shock absorber for preventing damage to the power device in case the mobile platform is involved in a crash.
