This paper presents an integrated optimal dynamics control of four-wheel driving and four-wheel steering (4WD4WS) electric ground vehicles via hierarchical control methodology. In the higher-level design, an LQR controller is proposed to obtain the integrated lateral force and yaw moment, according to their respective reference values. The lowerlevel(More)
In this paper, glucose respiratory quotient (RQ)-feedback control was developed for erythromycin production with a recombinant strain Saccharopolyspora erythraea ZL1004. RQ was confirmed to be an ideal online parameter for regulating glucose feed rate. Through feeding glucose to control RQ at 0.85 during 45-100 h and 0.95 during 100-185 h, erythromycin(More)
