Abstract

The Autonomous Submarine Surface Vehicle is a type of unmanned underwater vehicle. When the ship performs maneuvers, there are large Pitch and Roll motions. This research aims to control the stability of the Autonomous Submarine Surface Vehicle with Fuzzy. The first process is taking Pitch and Roll data followed by the Fuzzification process to change input data with firm values into Fuzzy values. The next stage is Inference by using the rules (if – then) and the Deffuzification process to change the results of the inference stage into output values. The last is the process of stabilizing the ship with a Thruster dc motor. When the system is activated, it has a time of 0.518 seconds faster to steady state than the deactivated system with a roll tilt of (plus) 11°. On the roll tilt of (plus) 20° the highest PWM rotation is 1600µs with a time of 9,342 seconds to steady state and the roll tilt is (plus) 11° with the highest PWM of 1500µs with a time of 4,335 seconds. Based on this research, the Fuzzy Method can control the stability of the Autonomous Submarine Surface Vehicle ship.

Abstract

The communication between microcontrollers and PLC has become an important technology development that needs to be enhanced. One of the reasons for the communication between these two devices is to facilitate the input process of data or information from sensors, which are responsible for detecting or measuring specific parameters. Not all sensors can be directly read by PLC, as some sensors have their own communication protocols or specific libraries that are not directly supported by PLC. Microcontrollers are often used as intermediaries between sensors and PLC. Microcontrollers can read sensor data and then convert it into a format that can be understood by PLC. Microcontrollers can perform flat processing tasks such as conversion and status evaluation to provide more relevant data, and then send this data to the PLC through a compatible communication protocol. In this study, the communication protocol used is the Host Link serial communication using the C-mode Command method. The communication testing conducted using 10 different data samples resulted in accurate values with an error percentage of 0%.
