The reliability of any embedded navigator in advanced vehicular system depends upon correct and precise information of navigational data captured and processed to offer trustworthy path. After reviewing the existing system, a significant trade-off is explored between the existing navigational system and present state of controller design on various case studies and applications. The existing design of controller system for navigation using error-prone GPS/INS data doesn‟t emphasize on sliding mode controller. Although, there has been good number of studies in sliding mode controller, it is less attempted to optimize the navigational performance of a vehicle. Therefore, this paper presents a novel optimized design of a sliding mode controller that can be effectively deployed on advanced navigational system. The study outcome was found to offer higher speed, optimal control signal, and lower error occurances to prove that proposed system offers reliable and optimized navigational services in contrast to existing system.

Fossil fuels leave behind harmful by-products upon combustion, thereby it causes a lot of pollution.Renewable energy is gaining more importance these days. But the problem with the renewable energy systems is its intermittent availability. Hybrid power system which combines various renewable sources is the next available option. This paper discusses the scheme of Solar-Wind Hybrid power system using multi-input power converter topology. Simulations are carried out using MATLAB/ SIMULNK. Charge controllers are implemented with MPPT algorithm. The hardware implementation of the controller is done using FPGA controllers. The experimental details are given and the results are discussed.  Index Terms-hybrid power system, PV, solar, wind, MPPT, controller, FPGA

This paper discusses the design and implementation of single phase PWM inverter using 8051 microcontrol-ler. The main features of 8051 based PWM inverter are simpler design, low cost, maximum range of voltage control and compact in size. The designed PWM inverter is tested on various AC loads like AC motor and intensity control of incandescent lamp in a closed loop environment
