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.

将塑料和橡胶与交联剂或接枝剂共混，通过反应挤出制造新型改性聚合物，例如 TPV（热塑性硫化橡胶）和接枝聚合物，是一个高度非线性且复杂的过程。高度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加工条件。从过程控制的角度来看，反应挤出代表了一个多变量非线性系统。简单的控制算法，例如 PID（比例、积分和微分）控制器不足以控制如此高度非线性的过程。 莱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出设备。除了该实验室外，先进过程控制和仿真 (APCS) 研究实验室还提供实时仪器和分布式控制系统 (DCS)，是实施先进控制方法的理想选择。
