Abstract

Different sectors of industry have a need for DC motors due to their benefits, such as substantial torque, absence of reactive power loss, no disruption to power supply, and precise control. Automation in control plays a crucial role in advancing science and technology. An effective control system must fulfill specified criteria, encompassing performance indices associated with accuracy, stability, and rapid response. An optimal control system is one fashioned through the optimization of performance indices, considered optimal when parameter values are chosen to maximize or minimize the selected performance index. In the context of DC motors. In the context of speed regulation using the Linear Quadratic Regulator optimal control technique, the optimization of performance indices involves configuring the Q matrix value. This, in turn, results in the generation of the K feedback amplifier matrix and the optimal L tracking matrix for the DC motor. The process is repeated for speed regulation in the DC motor using the Linear Quadratic Regulator optimal control technique, where performance index optimization is achieved by adjusting the Q matrix value, leading to the derivation of the K feedback amplifier matrix and the optimal L tracking matrix.

Abstract

The rapid and effortless evolution in different realms of this era includes the sustainable advancement of technology, exerting significant influence on various facets. The expansive nature of technology and information underscores its versatility. Observing these progressions, the ongoing development of science emerges as an inevitable outcome, drawing upon existing knowledge and perpetuating studies to enhance future functionality. The optimization of knowledge through the examination of its evolution proves instrumental in facilitating innovation for future generations, ensuring more efficient and ergonomic utilisation. So, considering the substantial electricity demands in the industry, which rely on evenly spread energy sources, it's crucial to find a method for efficiently managing this demand. This involves delving into the realm of science, particularly in the context of propulsion engines. Through research, one can explore how system optimization impacts the effectiveness of control methods like LQR and LQT, especially when additional noise is introduced to the DC motor load system.

Abstract

This research examines how the SWOT method is employed to determine the marketing strategy of PT PAL INDONESIA, aiming to explore the application of SWOT, using qualitative methods for data collection and analysis. The study reveals its findings through a combination of online and offline surveys. Online surveys were conducted via a Google Form to gauge customer satisfaction, operational performance, and user preferences. Offline surveys involved interviews with various stakeholders at PT PAL Indonesia, including senior management, engineers, and employees. The outcomes illustrate the strategic utility of assessing a company's strengths, weaknesses, opportunities, and threats. This underscores the significance of considering these elements within a company. The SWOT analysis plays a crucial role in formulating business strategies and aids PT PAL Indonesia in comprehending both internal and external factors impacting the company. By effectively leveraging SWOT analysis, companies can enhance their competitiveness, tackle challenges, and capitalize on opportunities for sustained long-term growth and success.
