Perancangan Alat Kontrol Digital - Analog dengan Menggunakan perangkat komputer

Abstract

This study is aimed to identify and to analyze the behavior output signal from Digital To Analog Converter (DAC) that combined with motor DC driver. But before the analysis, the design must be conducted. Typical motor DC is servo motor, it means that the motor can tum clockwise and counter clockwise. Behaviour of servo motor controller was linear, so the sistem can be named by linear motor controller. This study can we used for the research on the mechatronics field, especially on the agricultural engineering. From the experienced, it was found that the response from output signals in analog mode depend on load that conduct on the circuit. Clearly based on the result of analysis, it was found: (1) correlation between working voltage and performance of motor DC (rpm) was closed. (2) The output signal response on the driver was depend on the typical load. (3) Results from the testing show that driver can be controlled by linear mode (4) The adjustment of circuit was necessary to maintain the control systems stability Keyword: linear motor controller, servo motor controller
