Abstract

Kualitas bushing baterai yang diproduksi sangat dipengaruhi oleh kinerja mesin pencetak bushing baterai. Pada mesin ini, terdapat masalah ketidakstabilan suhu pada middle mold serta ketidakstabilan debit air dalam sistem pendingin saat terjadi gangguan, yang memengaruhi kualitas bushing baterai yang dihasilkan. Maksimum overshoot suhu yang mencapai 10,5℃ saat menggunakan kontrol on-off pada heater dan ketidakstabilan debit air dengan penggunaan valve manual menjadi permasalahan utama pada mesin ini. Pengembangan dan penelitian terus dilakukan guna meningkatkan kualitas serta meminimalisir cacat produk dengan menjaga kestabilan suhu dan debit air sistem pendingin pada middle mold. Berdasarkan literatur dan penelitian terdahulu, penggunaan kontrol PID mampu menstabilkan output aktuator yang dikontrol dengan membandingkan referensi input dan feedback output dari sensor yang digunakan. Pada proyek ini, diterapkan sistem kontrol PID pada heater middle mold menggunakan metode tuning Ziegler-Nichols 1, serta kontrol PID Modulating Control Valve (MCV) pada sistem pendingin middle mold dengan system identification serta tuning manual pada software MATLAB. Pada kontrol PID heater diperoleh parameter nilai Kp=4,35; Ki=0,0090625; dan Kd=522. Proyek ini berhasil menjaga suhu middle mold mesin saat produksi pada suhu awal 40,3℃ dengan rise time (10-90%) 1231 detik; maksimum overshoot 3,8℃; settling time 1351 detik; dan steady-state error 1,43%. Selain itu, simulasi kontrol PID MCV dilakukan pada software MATLAB sehingga didapatkan parameter nilai Kp=5; Ki=0; Kd=0,25; dengan karakteristik respons sistem rise time (10%-90%) 0,26 detik; settling time 0,9 detik; tidak ada overshoot; dan tidak ada error. Dalam penerapannya, kontrol PID MCV dapat menstabilkan debit air ketika terjadi gangguan dengan maksimum overshoot 0,04 L/min; settling time 3 detik; dan steady-state error 2%.

The quality of the battery bushings produced is greatly influenced by the performance of the battery bushing molding machine. In this machine, there are issues with temperature instability in the middle mold and water flow rate instability in the cooling system during disturbances, affecting the quality of the battery bushings produced. The maximum temperature overshoot reaching 10.5°C when using on-off control on the heater and the instability of the water flow rate with the use of a manual valve are the main problems in this machine. Continuous development and research are conducted to improve quality and minimize product defects by maintaining the stability of the temperature and water flow rate of the cooling system in the middle mold. Based on literature and previous research, the use of PID control can stabilize the output of the actuator controlled by comparing the reference input and feedback output from the sensor used. In this project, a PID control system was applied to the heater of the middle mold using the Ziegler-Nichols 1 tuning method, as well as PID Modulating Control Valve (MCV) control on the cooling system of the middle mold with system identification and manual tuning on MATLAB software. For the PID heater control, parameters obtained were Kp=4.35, Ki=0.0090625, and Kd=522. This project successfully maintained the middle mold machine temperature during production at an initial temperature of 40.3°C with a rise time (10-90%) of 1231 seconds, maximum overshoot of 3.8°C, settling time of 1351 seconds, and steady-state error of 1.43%. Additionally, a simulation of PID MCV control was conducted on MATLAB software, obtained parameters Kp=5, Ki=0, and Kd=0.25 with system response characteristics of a rise time (10%-90%) of 0.26 seconds, settling time of 0.9 seconds, no overshoot, and no error. In its application, PID MCV control can stabilize the water flow rate during disturbances with a maximum overshoot of 0.04 L/min, settling time of 3 seconds and steady-state error of 2%.
