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.
