Main contributions and achievements are as follows:A general non-equilibrium rigorous model for RDP is developed in this thesis. Based on the pseudo-homogenous assumption, two main factors reaction and separation are de-coupled, and an RDP model with the same format as that for a traditional distillation process is established. To solve the model with a large number of algebraic equations, modified M-K equations with tri-diagonal matrix form are developed based on the improved Separation Efficiency Functions, which greatly increases the iteration efficiency. This thesis also develops a general reactive distillation dynamic model. Through splitting of the differential variables based on SEFS, large-scaled differential algebraic equations can be solved with the improved Gear's algorithm which makes the dynamic model suitable for the on-line application. A simulation platform for the control loop design and evaluation of RDP by introducing control system equations into the dynamic model is also developed.A lactic acid purification pilot-scale RDP is investigated.

It thinks that the promotion of ESO system is the requirement to deepen the current state-owned enterprise reform and the construction of modern enterprise system. It is urgently needed by the hi-tech enterprises to attract talents and avoid brain drain. The long-term stimulation mechanism such as stock option has better effect in comparison with the traditional salary mechanism such as basic wage and annual bonus. Meanwhile, with the expansion of use scale of the long-term stimulation mechanism such as stock option and greater elasticity of the performance of the whole salary, the stimulation effect of the whole salary will be strengthened.

认为ESO制度的推行是当前深化国有企业改革，建立现代企业制度的要求，是高科技企业吸引人才、避免人才流失的迫切需要；其与基本工资和年度奖金等传统薪酬机制相比，股票期权等长期激励机制的激励效果更好；同时随着股票期权等长期激励机制使用规模的扩大，整体薪酬的业绩弹性增大，使整体薪酬的激励效果增强。

Thirdly, fuzzy control method and PID method were used respectively to design temperature self-adjustment controller of carbon fiber concrete laminate beam,by the MATLAB simulation it is found that the PID method has higher speed but is more sensitive to the fluctuation of system parameter ,it is suit to the regulating when the heat transfer coefficient fluctuates diminutively and the structure has little heat transfer with the environment;fuzzy control can be adapt to the parameter variety in a large scale , it is suit to the regulating when the heat transfer coefficient fluctuates greatly.

分别采用PID和模糊控制策略设计了温差自调节控制器，通过MATLAB仿真研究得出：PID方式具有更快的调节速度，但对系统参数变化较敏感，适合系统与外界对流交换较微弱，对流参数波动不大时的调节；模糊控制能够适应系统参数在较大范围内的变化，适合对流参数波动较大时的调节。
