  • Baek, CJ; Kumarawadu, S [Conference-Abstract]
    A novel paralleling interleaved discharging (PID) approach is presented to reduce the output ripple and continuous input current waveform in step-down switched capacitor (SC). Theoretical analysis and the computer simulation ...
  • Baek, CJ; Kumarawadu, S [Conference-Abstract]
    A new type of Inrush suppression circuit in SC buck converter is proposed. The method is realized by the hybrid of passive and active circuits. It adapts PIC micro controller to generate multi pulse to drive multi switches. ...
  • Jayendra, G; Kumarawadu, S; Piyasinghe, L [Conference-Abstract]
    This is an effort of employing good obstacle avoidance algorithms for unmanned surface vehicles (USV) which are already developed for unmanned ground vehicles (UGV). Previously developed Morphin algorithm is utilized for ...
  • Dharmapriya, TDK; Kumarawadu, S; Piyasinghe, LP [Conference-Abstract]
    Inertial sensors and inertial measurement units (IMUs) are widely used in navigation support systems, autonomous vehicle navigation, and vehicle motion control process. Inertial measurement based attitude determination and ...
  • Piyasinghe, LP; Kumarawadu, S; Jayendra, G; Dharmapriya, K [Conference-Abstract]
    Intelligent vehicles have to perceive their environment in order to navigate and avoid collision. This capability is also important in other applications such as mobile robot navigation, Automated Guided Vehicles (AGVs) ...
  • Jayendra, G; Kumarawadu, S; Piyasinghe, L [Conference-Abstract]
    This paper mainly describes designing and simulating a fuzzy logic-based navigational controller for unmanned surface vehicles. The controller considered in this study is consists a fuzzy based systems. MatLab framework ...
  • Kumarawadu, S; Ransara, SHK; Dissanayake, ASJ; Ranasinghe, N; Azmil, MM [Conference-Abstract]
    This paper mainly discusses about the design and realization aspects of collision avoidance (CA) controller which has the capability of interaction. ln other words, the controllers can talk with each other while operating ...

    This is an effort of employing obstacle avoidance algorithms for unmanned surface vehicles which are already developed for unmanned ground vehicles. Previously developed mathematical model and fuzzy-based navigational controller ...
  • Kumarawadu, S; Palayangoda, LK; Fernando, MM; Hemathunga, HPGS; Premathunga, DSM [Conference-Abstract]
    Single Switch Dual Output concept has been introduced through an idea of controlling two DC power outputs by using only one switch. The controlling strategy is to control one voltage output by duty the duty of the PWM and ...
