An Improved Active Disturbance Rejection Controller for Hydraulic Valve-Controlled Hydraulic Motor

An Improved Active Disturbance Rejection Controller for Hydr...

第三十九届中国控制会议

作者： Yifu hu donghui Li School of Electrical and Information Engineering Tianjin University

Hydraulic valve-controlled hydraulic motor is a commonly used power component. However, there is uncertain perturbation in hydraulic systems and active disturbance rejection control（ADRC） is able to estimate and compensate the disturbance in real-time, but the controller is not satisfying for the hydraulic system due to the buffeting of tracking process. In this paper, an improved ADRC controller is designed for the hydraulic valve-controlled hydraulic motor. The nonlinear function of the extended state observer（ESO） in the general ADRC controller is replaced by arc-hyperbolic sine function to alleviate the effect of buffeting. It can be seen that the improved controller is able to track the setting value without buffeting via simulation. Thus, the conclusion can be drawn that the improved ADRC controller is suitable for the hydraulic valve-controlled hydraulic motor in this paper since it can eliminate the buffeting and reduce the amount of tuning parameters as well.

Theconstruction of an integrative shuttle expression vector and potential utility was reported inEscherichiacoliandAnabaena(Nostoc) sp. strain PCC 7120. The vector comprised of the following elements: (a) an intergenic non-coding region fromAnabaenato facilitate its genomic integration (b) a strong functional PpsbAIpromoter fromAnabaenafor desired gene expression and (c) neomycin phosphotransferase gene with its own promoter for the selection of transfor-mants. The constructed vectorpAnFP was evaluated by cloning, transfer and expression of thegfpgene encoding green fluorescent protein. When ***. strain PCC 7120 were transformed, intensive green fluorescence produced by the products of GFP protein was observed. This result indicated that the integrative shuttle vector pAnFP can be promisingly used in genome transformation for expression of heterologous genes *** microalgae such asAnabaenaandNostocstrains.
