The state equation of induction motor with G-type parameters was established and a flux observer was designed based on U-N model. The speed adaptive law was deduced by the theory of Lyapunov stability. A method of model reference adaptive speed estimation based on the full order flux observer was proposed and a scheme of induction motor direct torque control without speed sensor was studied.

建立了基于异步电机G-型参数的状态方程，给出了基于U-N模型的定子磁链观测器；基于李雅普诺夫稳定性理论推出了速度自适应律，给出了基于这种全阶磁链观测器方案的模型参考自适应速度辨识方法。

ES cells were maintained on gelatin-coated dishes in Iscove's modified Dulbecco medium containing 0.1 mmol/L of nonessential amino acids, 2 mmol/L of L-glutamine, 0.1 mmol/L of monothioglycerol, 15% fetal bovine serum, and 1000 U/mL leukemia inhibitory factor. Embryonic bodies were firstly formed by ES cells with hang drip method in IMDM without LIF. Six-day-old EBs were trypsinized and the cells were resuspended at a concentration of （3-4）×109 L-1 cells per 1 mL of a 1:1 mixture of culture medium and Matrigel?

实验方法：将鼠胚胎干细胞株接种于被覆明胶的培养瓶内，加入含0.1 mmol/L非必需氨基酸、2 mmol/L L-谷酰胺、0.1 mmol/L二羟基丙硫醇、15%胎牛血清、1 000 U/mL白血病抑制因子的IMDM培养液。3 d后采用&悬滴法&使细胞在不含白血病抑制因子的上述IMDM培养液中形成胚胎体，6 d后胰酶消化得到胚胎干细胞，浓度调整为（3~4）×109 L-1，与Matrigel？
