Modeling and Control of a Twin Screw Extruder for the Production fo Modified ThermoPlastic Volcanizates

用交联剂或接枝剂共混塑料和橡胶，通过反应挤出生产新的改性聚合物，如热塑性硫化胶和接枝聚合物，是一个高度非线性和复杂的过程。高度的复杂性主要是由于化学反应性和选择性，对设备配置的敏感性，以及处理条件。从过程控制的角度看，反应挤压过程是一个多变量非线性系统。一个简单的控制算法，如PID（比例，积分和微分）控制器是不足以控制这样一个高度非线性的过程。在兰姆顿学院，独特的先进材料工程研究（AMER）实验室配备了中试规模的挤压设备。除了这个实验室，先进的过程控制和仿真（APCS）研究实验室提供实时仪器和分布式控制系统（DCS），这是实现先进控制方法的理想选择。

Blending of plastic and rubber with a cross-linking or grafting agent to manufacture new modified polymers such as TPVs (thermoplastic vulcanizates) and grafted polymers, by reactive extrusion, is a highly non-linear and complex process. High degree of complexity is mainly due to the chemical reactivity and selectivity, sensitivity to the equipment configuration, as well as the processing conditions. From the process control point of view, the reactive extrusion represents a multi-variable non-linear system. A simple control algorithm, such as a PID (proportional, integral and differential) controller is not sufficient for controlling such a highly non-linear process. At Lambton College, the unique Advanced Material Engineering Research (AMER) laboratory is equipped with a pilot scale extrusion equipment. In addition to this laboratory, the Advanced Process Control and Simulation (APCS) Research laboratory offers real-time instrumentation and distributed control system (DCS), which are ideal for implementing advanced control methodologies.
