Navigation problems of an agent in a virtual environment had been widely studied by many researchers. This paper presents a combination method based on Half-Sweep (HS) iteration and Kaudd Successive Over Relaxation (KSOR) to solve agent navigation problem in a simulated virtual environment. The proposed method, namely Half-Sweep Kaudd Successive Over Relaxation (HSKSOR), is used to obtain the solutions of Laplace’s equation known as harmonic functions which then be applied in the search algorithm to generate collision-free path for an agent to navigate from a specified start point to a target point. The results found that the HSKSOR offers faster computational approach with less computational time compared to the existing iterative methods.

This paper presents the development of a single-phase Active Power Filter (APF) to counteract harmonic currents which generated from a non-linear load. In this work, a single-phase Voltage Source Inverter (VSI) is used to rectify the pulsating nature of a distorted supply current generated by the non-linear load. Hence, the supply current becomes continuous, sinusoidal and in phase with a supply voltage waveform. Furthermore, it reduces the Total Harmonic Distortion (THD) level of the supply current, improve power factor and the quality of the power supply system. The VSI consists of 4 Insulated-Gate Bipolar Transistors (IGBTs) drive by an Active Pulse Width Modulation (APWM) technique. The APWM is generated using a Current Control Loop (CCL). This closed loop controller is constructed using a subtractor circuit, Proportional-Integral (PI) controller and a comparator circuit. The harmonic spectrum of the supply current waveform is compared with the IEEE 519 Standard. The simulation results have shown that the proposed APF based on VSI topology can improve the harmonic spectrums of the supply current according to the acceptance limit defined by the IEEE 519 Standard. Selected simulation results are presented to verify proposed operation.
