Abstract

In  this  paper  the  development  of  electric  vehicle  traction  control  based  on  state  of  speed  reconstruction  of vehicle model that has the same acceleration condition between tire and chassis is studied. Vehicle is accelerated if the friction force takes place between tire and road. However, the traction force decreases even tends to zero on slippery road and torque input produces a large slip. Evidently, tire slip can be reduced by decreasing the applied torque to the tire. So the basic principle of the proposed method here compares the real vehicle tire speed condition with the model to determine the torque in order to reduce the slip. Tire speed is controlled in order to follow the reference value that is calculated from the model. Tire torque input then can be controlled by applying the feedback that is obtained from the difference value of speed between model and real tire. Implementation of this method on a real vehicle shows that the control method effectively controls the tire speed of vehicle to follow the reference and reducing the slip. From the experiment the control  system performance in reducing slip has the result  of 9.8% for maximum overshoot, 3.1 second for rise time, and 8 second for settling time.

Abstract

Beban pendinginan merupakan komponen penting untuk melakukan perancangan sistem tata udara, karen beban pendinginan digunakan sebagai dasar untuk penentuan sistem dan kapsitas sistem yang akan digunakan dalam perancangan. Ada banyak metode yang bisa digunakan untuk melakukan perhitungan beban pendinginan, salahatunya adalah metode Radiant Time Series, metode ini bergantung pada deret faktor respons selama 24 jam yang digunakan untuk menghitung perolehan panas konduktif, dan bergantung pada deret waktu selama 24 jam untuk mengubah panas radiasi sesaat ke dalam beban pendinginan. Metode ini memiliki banyak prosedur dan detail perhitungan yang harus dilakukan. Maka dari itu dibuatlah aplikasi untuk membantu melakukan perhitungan, aplikasi ini dibuat menggunakan bahasa pemrograman JavaScript agar bisa digunakan multiplatform. Aplikasi ini berisi berbagai data yang dibutuhkan untuk melakukan perhitungan beban pendinginan, lalu menggunakan data tersebut untuk melakukan perhitungan secara bertahap dan memunculkan setiap detaildari hasil perhitungan dalam bentuk tabel, sehingga hasil dari perhitungan bisa menggambarkan keadaan yang sesungguhnya.

Abstract

Boolean expressions are an important result of a translation algorithm from a ladder diagram. Having a PLC and a ladder diagram on digital device programming has grown, VHDL requires translating back to boolean expressions that are equivalent to ladder diagrams to run in the program. Elements of ladder diagram-based programming not only consist of basic operations such as And, Or, or Not, but also contain additional basic elements such as comparators, timers and counters. In this paper we discuss a script-based programming that contains boolean expressions for each row of scripts, but represents a rung of a ladder diagram. Script-based programming developed using Javascript boolean expressions syntax is expected to be the beginning of a new way of programming I/O devices in addition to existing Structured Text programming methods. An I/O simulator based on web programming was built to visualize the written boolean expressions. The script consists of two parts, the main part is boolean expressions beside of scripts for graphical and other visualizations adapted to the Javascript writing syntax. Programing with use boolean expressions of ladder equivalents are more concise and minimize broad view in testing the course of programs with additional visualization of results. The timer algorithm is designed to be applied on a second time scale. The error value for on delay is around 0.062 seconds and for off delay around 0.046 seconds.Keyword: Boolean expressions, ladder, I/O, Javascript, simulator

Abstract

A refrigeration trainer is a working model of an existing system intended to support student learning in the characterization of refrigeration systems, especially their temperature profile. There are many ways to monitor temperature in refrigeration trainers, such as by implementing a temperature monitoring and control system based on Raspberry Pi 3 B +. This project uses the DS18B20 sensor and Raspberry Pi 3 B+ microprocessor. This system has various features such as temperature monitoring, on/off control for fans and compressors, online and offline data storage, and remote control. After 4 hours of testing, the prototype looked stable without any sudden increase or decrease in temperature values for all measurement point parameters. In addition, the error percentage value which is less than 10% shows that the DS18B20 temperature sensor used provides the best accuracy value and is considered adequate for this prototype.
