Abstract
Sistem pengaturan posisi pada Pneumatic-Hydraulic Combination
Control (PHCC) merupakan permasalahan tracking sistem mekanik.
Sistem PHCC merupakan kombinasi antara sistem pneumatik dan
hidrolik. Konsep tracking adalah bagaimana respon keluaran dapat
mengikuti sinyal referensi sedekat mungkin. Nonlinieritas pada sistem
PHCC terjadi karena penggunaan katup solenoid on/off yang terhubung
dengan silinder pneumatik-hidrolik Metode kontrol sliding mode
dirancang untuk meningkatkan kepresisian dan kecepatan dari silinder
pneumatik-hidrolik saat melakukan tracking sinyal referensi. Dengan
diterapkan metode ini, kecepatan dan kepresisian dari silinder
pneumatik-hidrolik meningkat dengan rise time yang dibutuhkan sistem
tanpa kontroler 11,3 detik menjadi 10 detik untuk tracking posisi
silinder. Kesalahan pembacaan posisi silinder yang semula 0,5 mm
menjadi 0,3 mm

In pneumatic system, pressured air that has high compressibility is used
as the transmission media. Pressure which produced in this system is
low. Using this media has weaknesses in example high compressibility.
Consequences, speed is slow and precission rate of cylinder is low.
Resolving this problem, Pneumatic-Hydraulic Combination Control
(PHCC) systems is applied which combination between pneumatic and
hydraulic system. This research discusses about PHCC system that
includes nonlinear system. Nonlinearity occur while the system is
changing from charging to discharging mode or vice versa. This method
has low sensitivity while applied to nonlinear system(s). The advantages
of applying sliding mode control, speed and precission rate of
pneumatic-hydraulic cylinder increased. Sliding Mode Controller be
able to drive system to track position. This has been proven by
experiment which shows cylinder’s rise time to get to desired position
was 10 seconds at 0.3 mm for any initial condition.
