The chief purpose of this research is to identify the variable vehicle parameters considering the important role of these data in vehicle active safety systems. Generally, implementing sensors to measure these parameters could raise the cost of the product. Parameters of the reference sedan car we focus on are total mass of the car, yaw moment of inertia and distance between the vehicle centre of mass and its front axle as well as vehicle velocity using least square estimation with variable exponential forgetting factor. The estimator equations are derived based on the bicycle model of vehicle. The performance of designed estimator is evaluated by virtual simulations performed with the aim of the full vehicle model in ADAMS/Car in different maneuvers. The obtained results show the accurate, prompt and appropriate performance of the estimator in parameter estimation.

Self-regulating polymer heating cables are widely used in industry and the commercial world. Their applications include process temperature maintenance, frost heave protection, floor heating, and snow-melting. The heating cables automatically adjust their power output to compensate for temperature changes. This paper demonstrates a numerical approach based on a 3D finite element model to evaluate the cable performance in a concrete slab for snow-melting applications. A variety of thermal conditions are investigated to simulate the ambient temperature changes. Experiments were carried out to validate the finite element model. The numerical results and experimental data are compared and presented.

It is required that the loitering aero vehicle with MEFP (Multi-Mode Explosively Formed Penetrator) in warhead plays its role to the largest extent in constraining the terminal angle. This article develops a guidance law that guarantees both the hitting target and its angle of fall. First relationship between the target and aircraft is established and its nonlinearity is linearized; next a parameter is introduced and through the change of reference point and the working on Riccati equation, the guidance law with optimum control method is achieved to gain the satisfied terminal angle. It is proved by simulation that the guidance law performs well in controlling terminal angle and the ballistic trajectory.

This paper deals with the problem of software sensor (state estimation) to study the continuous age structured model of a harvested fish population, in order to get an estimation of the biomass of fishes by age class. In our case the fishing effort is considered as a control term, the age classes as a states and the quantity of captured fish as a measured output. The continuous non-linear model is first represented by a Takagi-Sugeno multimodel. Next, we develop a technique for designing a multimodel software sensor (called also observer) corresponding to this system and show its asymptotic convergence. The design conditions are given in linear matrix inequalities (LMI) terms which can be solved efficiently using existing numerical tools. The simulation results demonstrate the effectiveness of the proposed method.

Mean Value Engine Models (MVEM) model the averaged dynamics of an automobile engine and have been used for the purpose of automotive control and fault diagnosis. Within-Cycle, Crank-Angle based Models (WCCM) are complex models that model the instantaneous dynamics of engine states and replace a real engine for simulation purposes. A WCCM was constructed on the simulation platform AMESim™. An MVEM was derived from this simulation data. The motivation for this work was to use this model in an MVEM based Fault Diagnoser

This paper addresses the application of the non real-time estimators, extended Kalman smoother and the two recently developed unscented Kalman smoother algorithms in deriving kinematic characteristics of a high maneuver flying target which is tracked with two passive sensors. Also the performance of these algorithms is compared over Monte Carlo simulations.

In this paper, an adaptive neural network controller was presented for a class of strict-feedback nonlinear systems with unknown time delays and input saturation. Based on the backstepping design technique, an adaptive controller was obtained by constructing an appropriate Lyapunov-Krasovskii functional. The saturation characteristic of the actuator was compensated by a compensator. It is proven that the semi-global uniformly ultimately boundedness of all the signals in the closed-loop systems was guaranteed. A simulation example was provided to illustrate the validity of the proposed approach.

A novel fluxgate digital magnetic compass system is introduced based on fluxgate technology and two axis dip angle sensor. The algorithms of magnetic compass orientation technology are introduced. The principle of peak detection approach and the approach of digit driver is researched. The system uses Atmega16L MCU to processes the data, and to avoid stability problem caused traditional RC analog drive circuit; digital square-wave signal from the MCU is applied to directly drive the fluxgate sensor. Furthermore, the system resolution factor is guaranteed by sampling the fluxgate signal with special ADC (16bit). It has already been successfully applied to some type of digital magnetic compass.

In this study, a new terminal converging PD control is developed for parallel robotic manipulators with bounded torque. By using decimal fraction power of tracking error, the proposed approach can achieve asymptotic stability with faster converging speed than conventional saturating PD control. In terms of LaSalle's invariance principle, the corresponding theoretical analysis is presented. Finally, an illustrative example is bench tested to validate the effectiveness of the proposed approach.

Guaranteed cost control (GCC) is considered for a class of uncertain nonlinear systems with time-delay. By using the linear matrix inequality (LMI) approach sufficient conditions of the existence of the GCC law are given, and the designing procedure of the control law is proposed. The closed-loop control law is robustly stable and the cost performance index is less than a given upper bound. Furthermore, a convex optimization problem with LMI constraints is formulated to design the optimal guaranteed cost controller for minimizing the cost of the closed-loop uncertain systems.
