And Performance

This paper presents the use of the dSPACE rapid control prototype (RCP) control system to implement a feedback control system for a conventional Boost DC-DC converter hardware to validate the converter's operation and performance during the research and development stage. The proposed system was implemented and tested using a conventional Boost DC-DC converter and a dSPACE (RCP) based control strategy. The advantage of employing this control platform for the converter is that it allows for the identification of design errors in the development process without the requirement for complicated control coding. Details of the DC-DC boost converter operations, the converter feedback dSPACE control system experimental setup and experimental test results are all presented in the paper. The results show that the system can conform to any set desired reference voltage.

To realize the online error analysis and verification of control strategy, it is necessary to simulate the states of the motion mechanism, and accurately to obtain the motion relationship between multi-axis and between motors. So a test and simulation system of multi-axis controller was designed. The system consists of a unit of real-time acquisition and analysis, a simulation unit of motor loads, a motherboard and a computer. Motor driving signals for multi channels are synchronously sampled and analyzed by the unit of acquisition and analysis. Motherboard is used to link the various parts. The working states of motor divers under loads are simulated by simulating the motor loads. In the industrial computer, the control effects of multi-axis control system are displayed by 3D simulation. Test results show that the system is stable and reliable, and has a certain application value.

Rotary Inverted Pendulum

In this paper we study the control system of single stage rotary inverted pendulum, and put forwards the controller design based on the core of STM32. In control strategy we use the classical control theory-PID control algorithm, which realizes the closed-loop control of rotating arm and swing rod for the single stage rotary inverted pendulum. The final test results show that the control strategy is effective.

This study aims to describe the process of developing a demonstration method using Student Activity Sheet (LKS) with an online similation approach on fluid material, and producing Student Activity Sheets that meet valid, practical, and effective criteria. This research is a development research using the model of device development according to Thiagarajan, without spreading stage. A limited trial was conducted in class XI IPA 1 MAN Majenanag odd semester of academic year 2017/2018 with 38 students. In this study, the data obtained from the validation by the validator, the results of student work on the test results of learning, and filling the questionnaire response students. Based on the analysis results obtained that the LKS development process refers to the model according Thiagarajan which is limited to the development stage. The result of the development is LKS with an online simulation approach on fluid material that meets the valid, practical, and effective criteria

Surge Control

Epstein, Ffowcs Williams and Greitzer presented in 1986 arguments that, provided small perturbation stability models were relevant to engine surge and rotating stall, then both could be avoided by active control. The idea was tested and validated on turbocharger compression systems at MIT and Cambridge University. Engine experiments are more difficult, the surge more violent and the signals usually contaminated by noise. This paper describes the early results obtained on a gas turbine engine subjected to the same control strategy. The control system can be switched on when the engine operates in violent surge and smooth operation is restored. This proof that the technique has practical relevance is interesting enough to report in advance of detailed investigations of its scope. This paper reports the experimental details, describes the relevant theoretical model and gives the first positive test results.

<p>The research is motivated not yet using CTL approach. In addition, the study provided yet foster the character value of students. This study aimed to the development of learning materials by using CTL approach with the integration of character value are valid, practical, and effective. The type of this research is research and development by using 4-D models. The stages of this research are define, design, and development. The define stage consists of analyzing of curriculum, students, and concept. Then, the learning materials as lesson plan, handout, student’s worksheet, and evaluation, were designed at design stage. The development stage was doing validity, practicality, and effectiveness test. The data of this research was collected by using validation instruments, questionnaire of students and teacher, observation and test instruments. The result of research with validity of the test results showed that the syllabus, lesson plans, teaching materials, worksheets and assessment sheets (cognitive, affective and psychomotor) developed very valid. The test results showed that the learning practicalities developed very practical. Based on the results of efficacy trials, it was stated that the developed learning very effectively used as learning tools are developed to improve the activity and competence of students in the cognitive, affective and psychomotor and behavioral character. And Those, learning materials by using CTL approach with the integration of character values are classification of very valid, very practical, and effective.</p>
