3D Platform Simulator Design Using Discrete Multi-Piston Actuators

Abstract

Generally, 3D simulator uses continuous feedback control system to control their actuator states. The objective of this article is to control the movement of actuators in compliance with 3D position required by simulator. This research uses discrete actuator for 3D simulator with four actuators that is open-loop controlled using Neuro-fuzzy control system. The actuator possesses linear pneumatic actuator with three pistons inside where each piston has independent intake. With the proposed design, the actuator able to give degree of discrete not only two (binary) values but also 26 combinations of discrete values. The 3D simulator proposed in this research have four actuators and two passives like-actuator. This configuration gives 4 degrees of freedom of platform movement. Applying force to the actuator using discrete output controller make possible to get more precise in terms of control and movement of the simulator that very useful for many force control applications.
