碩士 === 國立勤益科技大學 === 化工與材料工程系 === 95 === Abstract This thesis discussed that the parameters (the fraction of the total volume which is perfect mixed) and (the fraction of the feed entering the zone of the perfect mixing) of the non-ideal mixing affect on the dynamic behavior CSTR with an exothermic reaction . This thesis also discussed the effect of the non-ideal mixing on the system gain; dynamic response; inverse response, overshoot and pole-zero cancellation by using Laplace Transformation. Furthermore, we study the effect of the non-ideal mixing on the region of static stability, dynamic stability and multiplicity. As to the control field, this thesis studied the effect of the non-ideal mixing on the continuous and discrete samples-data control system with proportional control. The influence of the non-ideal on the stable region of the proportional gain was discussed in the continuous control system. For the discrete samples-data control system, besides the sampling time determine the stable region of the proportional gain, the non-ideal mixing is another important factor. The analytical results of this thesis will helpful for chemical reactor design and control.
