Designing a 2-Degree of Freedom Model of an Unbalanced Engine and Reducing its Vibrations by Active Control

Abstract: In this paper, a 2-degree of freedom dynamic model of an unbalanced rotary engine is designed, in a manner that has the effect of modal coupling. After designing the dynamic model in order to reduce the vibrations generated due to the unbalancing mass and modal coupling, the active force control (AFC) method is implemented along with a conventional proportional integral derivative (PID) controller with linear actuators, meaning that the AFC loop is applied as a supplement to the conventional PID controller.

“…Dengan demikian, parameter pengendali sebaiknya ditala dengan baik, sehingga AQM dapat dengan cepat mengatur queue length ke nilai yang diharapkan dan menjaga kestabilan dengan sedikit osilasi. Nilai parameter yang tepat dapat menghilangkan disturbance atau error yang merugikan bagi sistem proses [12]. Dua kriteria kinerja jaringan yang diharapkan diantaranya adalah mendapatkan queuing delay yang pendek dan utilitas link yang tinggi.…”

“…However, the parameter controller should also be properly tuned, so an AQM controller can quickly regulate queue length to the desired value and maintain stability with less oscillation. The proper parameter value can discard disturbance or error that has advantages for the system process [13]. Two criteria of the desired network performance that are expected to be achieved are short queuing delay and high link utilization [14].…”

“…This method can reject very large disturbances. The PID controller has been discussed in the literature (Mohebbi & Hashemi, 2016;Mohebbi & Hashemi, 2017). However, this has a weakness, which is the presence of new disturbance known after measuring output.…”
