Cold enzymatic hydrolysis conditions for bioethanol production were optimized using multi-objective optimization. Response surface methodology was used to optimize the effects of α-amylase, glucoamylase, liquefaction temperature and liquefaction time on S. cerevisiae biomass, ethanol concentration and starch utilization ratio. The optimum hydrolysis conditions were: 224IU/g starch α-amylase,...
The line induction motor (LIM) is widely used for its some virtues due to the development of the sinusoidal pulse width modulation (SPWM) and vector controller (VC) technologies. Both the position loop and current loop are the necessary feedback control elements for the motor controller for it is efficient, flexible and anti-interference. As usual, the position loop for the LIM can be fulfilled by...
