摘要： In the present invention, a Smith predictor enhanced PID controller, SP-PID, is proposed. A tuning parameter Ksp is devised and the SP-PID controller would be gradually transformed from a PID controller to a Smith predictor as Ksp changes from 0 to 1. Properties of the SP-PID are explored and the design procedure is given to ensure a certain degree of robustness. Simulation results clearly indicate that the SP-PID takes advantage of the SP when small modeling error is encountered and it is gradually detuned to a PID controller, a user-friendly controller, when the model quality degrades. Moreover, the controller and its design procedure can be implemented in current process control computers with virtually no extra hardware cost.

摘要： The method and apparatus for improving the esterification procedure, in particular for improving the esterification procedure to obtain an ester of low carbon number such as the ethyl acetate and the isopropyl acetate, are provided. By means of the provided method and apparatus, the conversion ratio of the esterification procedure is significantly increased and hence an ester product of a relatively high purity, up to the industrial specification, is obtained.
