Mechatronics Application Using Characteristics Polynomial Control Approach With Case Study: Development of A Simulated Air Speed Indicator for Helicopter Simulator

摘要

A helicopter simulator has to be built to fully resemble the real cockpit environment including its instrument indicating air speed. This paper is aimed to apply mechatronics technology in development of a Simulated Air Speed Indicator (SASI) that can be used for a helicopter simulator. This indicator has a pointer which indicates a certain value at the dial depending on the simulated air speed signal sent by the host computer. The driving mechanism of this mechatronics system is composed mainly of dc motor, reduction gear, pointer and potentiometer. An analog positioning controller has been developed based on characteristics polynomial control approach. The performance of the developed instrument was validated through step response and precision repetitive experiments. From the experimental results, it is obtained that the controller with proportional gain of K_p = 30 gives steady state error of 0.14% and repetition error of 0.3 (knots).
