Furthermore, it’s a rapid, high-effect and economical method in the biomass material pretreatment. In this study, microwave-based heating was used for biomass material pretreatment, and Napier grass(Pennisetum purpureum) was chosen as the pretreatment target. Taguchi Method is applied to optimize the parameter with fewer experiment times, the optimal condition is vessel water with level two, 150c.c., heating power with level one, 50%, Pennisetum purpureum with level one, 5g. After optimizing the parameter, System Identification Method is used to establish the mathematic structure, system order and characteristic equation which approximate the real system. The simulation result shows that ARX (Auto-Regressive eXogeneous) model with the eighth order could represent the real model which the Fitting is 99.13%. The results demonstrate that microwave-based pretreatment with Taguchi and System Identification Method is an efficient way to improve the efficiency of biomass material pretreatment.
