In the recent years,engineering new-to-nature CO_(2)-and C1-fixing metabolic pathways made a leap ***,artificial pathways promise higher yields and activity than natural ones like the Calvin-Benson-Bassham(CBB)*** question remains how to best predict their in vivo performance and what actually makes one pathway“better”than *** this context,we explore aerobic carbon fixation pathways by a computational approach and compare them based on their specific activity and yield on methanol,formate,and CO_(2)/H_(2)considering the kinetics and thermodynamics of the *** pathways found in nature or implemented in the laboratory,this included two completely new cycles with favorable features:the reductive citramalyl-CoA cycle and the 2-hydroxyglutarate-reverse tricarboxylic acid cycle.A comprehensive kinetic data set was collected for all enzymes of all pathways,and missing kinetic data were sampled with the Parameter Balancing *** and thermodynamic data were fed to the Enzyme Cost Minimization algorithm to check for respective inconsistencies and calculate pathway-specific *** specific activities of the reductive glycine pathway,the CETCH cycle,and the new reductive citramalyl-CoA cycle were predicted to match the best natural cycles with superior productsubstrate ***,the CBB cycle performed better in terms of activity compared to the alternative pathways than previously *** make an argument that stoichiometric yield is likely not the most important design criterion of the CBB ***,alternative carbon fixation pathways were paretooptimal for specific activity and product-substrate yield in simulations with C1 substrates and CO_(2)/H_(2)and therefore hold great potential for future applications in Industrial Biotechnology and Synthetic Biology.

Adaptive neural network control of a 2-DOF helicopter system considering input constraints and global prescribed performance

引用

Science China(Information Sciences) 2024年第7期67卷 224-239页

作者： Zhijia ZHAO Jiale WU Zhijie lIU we HE C.l.Philip CHEN School of Mechanical and Electrical Engineering Guangzhou University School of Intelligence Science and Technology and Key laboratory of Intelligent Bionic Unmanned Systems of Ministry of Education University of Science and Technology Beijing School of Computer Science and Engineering South China University of Technology Pazhou lab

In this study, an adaptive neural network(NN) control is proposed for nonlinear two-degree-offreedom(2-DOF) helicopter systems considering the input constraints and global prescribed ***, radial basis function NN(RBFNN) is employed to estimate the unknown dynamics of the helicopter system. Second, a smooth nonaffine function is exploited to approximate and address nonlinear constraint functions. Subsequently, a new prescribed function is proposed, and an original constrained error is transformed into an equivalent unconstrained error using the error transformation and barrier function transformation methods. The analysis of the established lyapunov function proves that the controlled system is globally uniformly bounded. Finally, the simulation and experimental results on a constructed Quanser's test platform verify the rationality and feasibility of the proposed control.
