Abstract

This concept introduces FSASMC (Fuzzy Self-Adaptive Sliding ModeController), which aims to check the movement and accuracy of the cylinder piston rod. Pneumatic control systems are widely used in our society, especially in the industrial sectors and in the automatic machine such as accuracy, safety, higher durability and stability, fast-moving speed, and cost-effectiveness in terms of price and maintenance. However, due to the highly non-linear responses of the pneumatic system, the controlling position of the pneumatic system is still a difficult task. The important part of controlling the pneumatic system for various movements is to provide a stable pressure in the chamber, and the operation of the piston rod is to minimize friction in a variety of ways. It is precisely controlled by the input. Therefore, FSASMC has been proposed to solve dynamic pressure stability and fast response problems by using fuzzy adaptive tuning of fuzzy logic control (FLC), through SMC (sliding mode control). The proposed FSASMC was verified using a pneumatic proportional valve with a double-acting cylinder dynamic model device. The emulation analysis focuses on steady-state error performance indicators, end performance standards, and adjustment parameters for the gradual hysteresis effect of cylinder chamber pressure and compared with CFSAPID.
