This paper presents an investigation of the reflectivity performance for hollow pyramidal shape microwave absorbers. The pyramidal absorbers used in this study is constructed using four 15cm-pyramidal absorbers stacked on each other to equal the height of one single 45cm-absorber. The wave frequency ranging from 8GHz to 12 GHz was chosen for simulation and measurement of the absorber performance....
This paper present a autoregressive with exogenous input (ARX) was applied in modelling of steam distillation pot system. The system of steam distillation pot are design with special specification interm of material and shape additional with induction heating system that provide a new technologies in extraction of essential oil to fullfill demand for this industry. The performance of ARX was investigates...
This paper present a model predictive control (MPC) that was proposed to implement at plant steam distillation pot with induction heating system. By using the ARX model structure, the model predictive control was design to control of steam temperature. Since the steam temperature play important role during the extraction of essential oil, important to researcher to find the control technique to optimize...
This paper present the characteristic of steam distillation pot where induction heating system were introduced as heating element. The induction heating system was choose because of green technology provided by it and had a high efficiency to compare with other heating element. This plant was developing to use in extraction of essential oil based on steam distillation column. The characteristic of...
