(H2): Innovative environment has a positive effect on technology innovation, while regional differences and temporal variations of effect size exist. There are many arguments about the relationship between enterprise scale and innovation efficiency [35,36]. For instance, Pavitt, Robson and Townsend (...
Additionally, by the deduced flux-angle-difference derivative equation, the scheme of flux-angle-difference feedback control (FADFC) is presented. In Section 4, by the simulation experiments, comparison between the DTC and the proposed FADFC strategy illustrates that the steady-state performance can...
