Abstract: Turbocharging the internal combustion engine(ICE) is to increase the power density of the engine or known as the downsizing of the engine. Large amount of heat energy is wasted through the exhaust manifold, coolant, convective and radiate heat transfer. The amount of heat loss generated to the surrounding by operating turbine volute will affect the service life of some automotive components. The current material tungsten used for heavy duty automotive turbine volute casing is heavier and costly if to compare to a new suggested material nickel with thermal barrier ceramic coating as an alternative.Thermal barrier coating is an alternative method for insulating cheaper and lighter engineering components operating in extreme temperature condition, there exist different coating techniques, but high installation cost and high technical skills requirement have restricted their widespread acceptance. The need of simple and cost effective thermal barrier coating has become necessary for the al

Abstract: This paper proposes an observer design for piecewise nonlinear systems via observer linearization. The model is a piecewise multi-linear (PML) system, a nonlinear approximation, and fully parametric. Feedback linearization is applied to stabilize PML control system. However, since exact observer linearized conditions are more conservative than exact feedback linearized ones, the exact observer linearization can be applied to only a few nonlinear systems. This paper shows the PML model based linearized observer can be applied to a wider system than the conventional one. We apply the proposed method to TORA (Translational Oscillator with Rotating Actuator) system which is one of the benchmark problem for nonlinear control. Example is shown to confirm the feasibility of our proposals by computer simulation.
