The spiral torsion spring‐based mechanical elastic energy storage (MEES) device presented previously with inherent characteristic of simultaneous variations inertia and torque is disadvantage to be actuated by conventional control method. This study proposes an improved non‐linear backstepping scheme based on combination recursive least squares (RLS) differential evolution (DE) optimisation regulate permanent magnet synchronous motor (PMSM) at a very low speed MEES effectively. For this...
Carbon nanotubes (CNTs) are potentially important biomaterials because of their chemical, physical, and biological properties. Our research indicates that CNTs exhibit high compatibility with bone tissue. The guided regeneration (GBR) technique is commonly applied to reconstruct alveolar treat peri-implant defects. In GBR, defects covered a barrier membrane prevent the entry nonosteogenic cells such as epithelial fibroblasts. also maintains space for new formation. However, mechanical...
Biogeography based optimization (BBO) is a new competitive population-based algorithm inspired by biogeography. It simulates the migration of species in nature to share information. A hybrid BBO (HBBO) presented paper for constrained optimization. By combining differential evolution (DE) mutation operator with simulated binary crosser (SBX) genetic algorithms (GAs) reasonably, proposed generate promising solution instead random basic BBO. In addition, DE still integrated update one half...
For the technology of mechanical elastic energy storage utilizing spiral torsion springs as media presented previously, a global multivariable control algorithm based on nonlinear internal model principle under multiclass external disturbances is proposed. The with nonharmonic periodic characteristics are generated by systems. New equations designed to estimate disturbances. On basis constructing law nominal system, state feedback controller guarantee closed-loop system globally uniformly...
Drilling of large-diameter boreholes is regarded as an effective measure for rockburst prevention. By investigating the morphological characteristic and evolution plastic zone in borehole surrounding rock, pressure-relief mechanism was ascertained, engineering application assessed 13230 working face Gengcun Coal Mine, Henan Province, China. The results showed that (1) rock appear circular, elliptical, butterfly shapes, which maximum size wings several times larger than diameter; (2) under...
Based on a brief review current harmonics generation mechanism for grid-connected inverter under distorted grid voltage, the harmonic disturbances and uncertain items are immersed into original state-space differential equation of inverter. A new algorithm global rejection based nonlinear backstepping control with multivariable internal model principle is proposed exogenous uncertainties. type class constructed. application law nominal system, adaptive state feedback controller combined...
