In semi-active suspension control, comfort and road holding are two essential but confl icting performance objectives. In a previous work, the authors proposed an LPV formulation for semi-active suspension control of a realistic nonlinear suspension model where the nonlinearities (i.e the bi-viscous and the hysteresis) were taken into account an H/LPV controller to handle the comfort and road holding was also designed.

This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence increases the cost and size of the drive system. These problems are eliminated by speed sensor less vector control by using Extended Kalman Filter and Back EMF method for position sensing. By using the EKF method and Back EMF method, the sensor less vector control of BLDC is implemented and its simulation using MATLAB/SIMULINK and hardware kit is implemented.

System Defining the state diagram, how to make a state diagram and where the system will stand if it is in one state.
说明: Consider a precision structure subjected to varying thermal conditions unless carefully designed, it will distort as a result of the thermal gradients. One way to prevent this is to build the structure a thermally stable composite material this is the passive approach.

Simulation and Performance Analysis of AODV, TORA
This report is about the development of efficient electric power conversion solutions for photovoltaic panels. Different solutions are presented and an overall perspective is shown. From the characteristics of the photovoltaic panels to the power grid all aspects are mentioned briefly. A three state commutation cell topology is chosen for a more detailed analysis, simulation is made and a prototype is built. Several tests reveal the characteristics of the chosen topology. Propose of this report is to introduce the necessary knowledge for further investigation of the three state commutation cell as well as its control by MPPT
