- ItemA Model & Framework for University & SMEs Collaborations(NSBM Green University, 2024-03) Samarakoon, K.S.; Kulatunga, S.L.In the era of innovation and knowledge exchange, fostering effective collaborations between universities and Small and Medium-Sized Enterprises (SMEs) has emerged as a critical aspect for mutual growth and societal advancement. This paper introduces a robust model and framework meticulously crafted to enhance and streamline collaborative endeavors between universities and SMEs. Rooted in a thorough examination of existing literature and enriched by empirical findings from real-world case studies, the proposed model amalgamates pivotal elements crucial for the success of such partnerships. It encapsulates organizational structures, resource allocation mechanisms, and effective communication strategies, thus paving the way for fruitful and sustainable collaborations.
- ItemAnalysis of PID (Proportional–Integral–Derivative) Controller for Inertial Stabilize Platform for Naval Vessel Weaponry Systems(NSBM Green University, 2024-03) Kulatunga, S.L.; Perera, C.; Perera, D.Ship motion analysis is crucial for understanding the complex movements vessels experience at sea, encompassing rotational and translational motions. These movements, such as pitch, roll, yaw, surge, sway, and heave, impact ship stability and safety. Conventional stabilization systems face challenges in accurately predicting ship orientation due to the dynamic nature of external and self-generated forces. This paper proposes a Proportional-Integral-Derivative (PID) controller with controlled feedback to enhance stabilization, particularly for weapon and tracking systems. Motion segregation simplifies the control system by focusing on training and elevation angles. Noise mitigation techniques, including fast Fourier transforms and Kalman filtering, address inherent ship noise factors. The system architecture integrates various components, enabling precise control and stabilization. The modified PID controller with tachometer inputs demonstrates smoother stabilization and operational accuracy, enhancing system performance in yaw and pitch motions. This research contributes to the development of effective stabilization systems for maritime applications, ensuring ship safety and operational effectiveness.
