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.
本论文针对车载异步电机在矢量控制器所遇到的问题:定转子电阻随温度变化及随电机饱和程度变化的转子电感及定子电感而影响电机调速性能提出一套完整的解决方案:分析了电流型逆变器和电压型逆变器在实现矢量控制时控制器参数的计算,分析出对于电流型逆变器在采用定子磁场定向时,其性能同时具有矢量控制和直接转矩控制两者的优势,并对电压型逆变器在转子磁场定向下的模型进行了仿真研究;建立异步电机非线性模型,推导出考虑磁饱和时异步电机在同步旋转坐标系及静止坐标系下的方程,并做出了仿真结果,建立异步电机在非线性模型下的矢量控制调节器的PI参数设计,在实际应用中,若忽略电机电感的动态变化,可以根据当前的磁路饱和状态而在线修正电感参数,从而将非线性方程线性化,降低控制器的复杂度;考虑到电动汽车在起动和加速超车时需要电机有最大转矩输出,本文讨论在逆变器容量一定和电池供电能力有限的情况下电机最大转矩输出问题;推导了异步电机扩展降阶、离散卡尔曼滤波方程在线辨识转子时间常数和转子磁通,用于实现高性能的矢量控制算法,并给出了仿真结果;推导出了电动汽车恒转矩给定的闭环回馈制动系统,实现了电动控制模型和制动模型的统一,而且结合铅酸电池最大充电电流的要求,为制动转矩在线给定建立了数学模型;设计了基于双DSP系统的高性能矢量控制器软硬件框图,并以大量实验数据说明矢量控制在电动汽车应用的实际应用状况。

All enhancers did not significantly change the transcorneal lag time of ENX. The irritancy of poloxamer and Azone was observed.? The results of in vitro release studies showed that the ENX gel based 3% HPMC K4M and 3%HPMC F4M povided sustained release of the drug over an 8-h period in vitro.Diffusion area has significantly effect on drug release, and pH value of medium and rotation rate have effcet on drug release.However, the diffusion shield has no effect on drug release. The P_ value of the preparation based on 3% HPMC F4M was 1.34-fold of conventional eye drops of ENX.
体外溶出度试验结果表明,以3%的HPMC K4M和F4M为基质制备的ENX凝胶剂的体外释放行为符合眼用缓释制剂的要求;体外释放度影响因素试验结果表明,释放面积对释放度有显著性影响,pH值和转速略有影响,而扩散屏障没有影响;离体角膜透过实验结果表明,以F4M为基质制备的凝胶剂中ENX的表观渗透系数P_(app是对照组的1.34倍,说明F4M与眼角膜的相容性较好,是一种理想的眼用制剂增稠剂,可以在眼用制剂中广泛采用。

The thesis gives a macro explanation and grasp which is based on theoretical foundation, social surroundings and developing trend, explains the possibility and necessity of its appearance and discusses the developed process of its object which covers not only real property but also all asset. The author analyzes beneficial weight, systematic ideal and legal values, then clarifies that the legal system needs profound juristic basis. By using the method of comparative analysis, the author expounds the requirement of applicable conditions in other countries and analyzes its deficiencies in the Contract Law of Peoples Republic China. From the angle of legal effect after its application, the author analyzes the differences in rights and duties between legal nexus among them (the owner, the leasee, the leaser) and pure bargain relation, lease relation. The author thinks applicable range of the legal system may be enlarged and be analogized to financial lease and over the property of another. In the end, it puts forward the perfection suggestions of the legislation of the system of no break of lease with bargain.
