ABSTRACT Aiming at problems of trans-vector controller in a vehicle-carried induction motor such as variable rotor and stator resistance following motor temperature, and their inductance varying with flux saturation degrees. Firstly, CSI and VSI are introduced, for CSI, it can hold the advantages both FOC and DTC using stator flux directional, PI parameter and simulation are also introduced. Secondly, equations of IM in the synchronous rotary frame and its static counterpart, as figuring in the saturation condition of magnetic field, are dealt in this paper and the simulation results are presented. Thereafter, the parameter designing of PI trans-vector controller is processed, which features the non-linear model. In practical realization, as neglecting the dynamical change of motor inductance, this paper employs online modification of inductance parameters, according to the flux saturation, then transforms the non-linear equations into linear ones, and so compacts the structure of controller. Thirdly, in view of the maximum torque output is extraordinary requisite when Electrical Vehicle start up, accelerate, and overtake, this paper issues the maximum torque when both inverter and battery capacity is corporeally definite. Fourthly, on-line differentiating and analyzing both rotor's time constants and its flux by using the expanding order reduction and discrete Kalman filter equation are fathomed, in order to realize high-performance trans-vector algorithm, and also the simulation results are presented. Fifthly, the close-loop regenerative brake system, when the EV's torque is set constant, is deduced; at the same time, unification of electric drive model and brake model is executed. Combined with maximum charge current demands, the mathematical model for online yielding torque as a demand.

Or 10.40% of the variation was partitioned among voltinism populations. The Nm (4. 3065) showed that there was to some extent gene flow among three voltinism populations. The average Nei's genetic identity was 0.9637. The genetic distance between V1 population and cultivated V1 population was the biggest (0.0438) and the less was 0.0370 between V1 population and V2 population.
Nei基因多样性指数也是2化群体最大(0.2631),1化群体次之(0.2485),培育1化性群体最小(0.1709),3个群体之间的遗传分化系数为0.1040,即3个化性群体之间的遗传变异占到总遗传变异的10.40%。3个化性群体之间的基因流达到4.3065,表明化性群体间存在着一定程度的基因交流。3个群体之间的遗传一致度为0.9637,遗传距离以培育1化性群体与1化性群体最大(0.0438),以1化群体与2化群体最小(0.0370)。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.
对于同一断面,靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内,朝水面方向各测点气泡个数分布最大值呈减小趋势,而其对应尺寸则呈现变大趋势;在靠近槽底,个数分布表现得比较集中,而在水面附近气泡个数分布曲线表现得低而平缓;实验条件下,整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方;气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大,且越接近掺气水流的水面,增加速度越快,最终趋于无穷大;气泡总数在掺气发展区内是沿程增加的,当掺气水流发展到一定程度后气泡总数就基本保持不变了;在同一断面上,各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。
