Wheel skidding or spinning is dangerous for driving vehicles, and compared to conventional vehicles, electric vehicles are more easily to slip during driving on slippery road. In this paper, a novel traction control method based on wheel-slip control is proposed to improve the safety and stability of electric vehicles. Considering the high nonlinearity and uncertainties of the traction system, this paper takes use of the feedback linearization methodology to design a nonlinear controller to achieve the tracking control for wheel slip. Meanwhile, to enhance the robustness of the controller, a integral action is introduced. As the controlled variable, the desired value of the wheel slip is required in the traction control system, this paper adopts the so-called Burckhardt's model to make online calculation for it. In order to demonstrate the effectiveness of the proposed method, simulations were conducted in different road conditions, and all the simulation results showed that the wheel-slip controller could produce a fairly good control performance.

Resolvers are rugged absolute position transducers which are widely used in various servo systems. The main shortcomings of resolvers are their nonlinear output signals, and therefore additional process is needed to obtain the linear angular signal. This paper presents a new resolver to digital converter (RDC) design method based on the extended state observer (ESO) with the advantages of noise insensitivity and higher tracking accuracy. An alternative demodulation strategy is also suggested where the output of resolver is sampled at two critical points. Such a treatment can realize demodulate resolver's output more accurately. Finally, simulation and experiment results are given with respect to a full FPGA digital system.

This paper is concerned with the problem of quantized H∞ filtering for a class of continuous-time Markovian jump linear systems with defective mode information. By virtue of a mode-dependent logarithmic quantizer, the measurement output of the plant is quantized, and the defective mode information in the Markov stochastic process simultaneously involves the exactly known, partially unknown and polytopic-type uncertain transition rates. By fully exploring the properties of transition rate matrices, together with the convexification of uncertain domains, a new quantized H∞ performance analysis criterion is first derived and then the filter synthesis is developed. It is shown that via a linearisation procedure, a unified framework can be developed such that both the full-order and reduced-order filters can be obtained by solving a set of linear matrix inequalities. Finally, an illustrative example is given to show the effectiveness of the proposed design method.

The method of designing the H∞ three-delay controllers for systems with time delay is investigated in this paper. The advantages of the controllers based on the delay modules lie in that it is easy to implement and it can be implemented in the occasions that ordinary controllers cannot be implemented. The three delay modules introduced into the controller is to improve the performance of the controlled system. Based on the complementary sensitivity function, the parameters of the three-delay controller are optimized with H∞ performance. Then, the problem of finding the set of the H∞ three-delay control parameters satisfying the certain H∞ performance is converted to the problem of stabilizing the quasi-polynomials which can be solved by using the D-composition method. Finally, the set of the three-delay control parameters is derived by finding the intersection of stable region and H∞ region. The simulation results verify the effectiveness of the proposed method.

For scaled MOSFET devices, normal operation of devices is seriously affected due to static gate tunneling leakage currents with ultra-thin gate oxide of MOSFET, and the novel MOSFET devices based on strained Si are similar to bulk Si devices in the effects. To illustrate the impacts of gate leakage current on performances of novel strained Si devices, a theoretical gate tunneling currents predicting model by integral approach following the analyses of quasi-two-dimension surface potential is presented in this paper, and on the basis of theoretical model, performances of NMOSFET devices were quantitatively studied in detail using ISE simulator including different gate voltage and gate oxide thickness. The experiments show that simulation results well agree with theoretical analysis, and the theory and experimental data will contribute to future VLSI circuit design.

Despite the fact that current device works significantly well on the utilization of geothermal, the management is still extensive and relies on human experiences mainly. For such reasons, the device parameters cannot be flexible enough to make full advantage of the device and the geothermal cannot be fully utilized. To solve this problem, this paper analyzes and compares some existing expert system based on their different knowledge, and summarizes the knowledge representation, common reasoning strategies, key issues such as forward chain, backward chain of the expert system and finally illustrates a practical and feasible automatic monitoring system of the step utilization of deep geothermal well based on expert systems.

This paper addresses the beam pattern analysis in uncertain environment. Assuming that beamforming is achieved along one given receiver direction, the beam pattern is controlled via the sensor distribution to make different goals. Given two different applications, we show that the sensor nodes are located in a straight line perpendicular to the receiver direction, different distance between the sensors contributes towards separate purposes, respectively. Simulation results are provided to validate the effectiveness of our approach.

A typical constrained mixed-integer nonlinear program: truss sizing and shape optimization under multi-loading cases and complex constraints is investigated in this work. A laconic adaptive penalty function is employed to handle the structural stress and local buckling constraints. The Covariance Matrix Adaptation Evolution Strategy (CMA-ES) is adopted to update the structural design variables. The effectiveness and efficiency of proposed hybrid algorithm is verified by a benchmark tower optimization problem. Numerical results indicate that the performance indicators of present work are better than those shown in the literature.
