In this paper, a novel double-sided direct-drive linear generator based on switched reluctance principle is proposed. In order to acquire a higher power density, the optimization of structure parameters for the double-sided linear switched reluctance generator (DLSRG) is carried out. To observe the nonlinear phenomena in SR generator, two dimensional (2D) magnetic static field distributions is obtained. For imitation of real-time operation, transient magnetic field is analyzed by finite element method (FEM). Then through a series of simulation and analysis, a group of appropriate parameters for the DLSRG are obtained. It is expected that the novel direct-drive generator finds its applications in power conversion fields such as wave power utilization. © 2011 IEEE.

A novel two-dimensional (2D) direct-drive generator based on switched reluctance principle is proposed in this paper. Due to its unique structure, the device is considered as a 2D power generator for sustainable energy utilization such as wind and wave energy with multidimensional motion forms. The generator has the advantages of simple structure and elimination of mechanical gears and rotary-to-linear motion converters. In this paper, a three dimensional (3D) mechanical model of this generator is designed and finite element analysis (FEA) is applied to simulate the model. From the simulation results, the coupling effect between each direction of power generation is negligible and each phase can be controlled independently. It is expected that the planar switched reluctance generator (PSRG) finds its potential applications in energy utilization area. © 2011 IEEE.

The linear switched reluctance motor (LSRM) is a new kind of direct-drive actuator, however, it is very difficult to build an exact theoretic model for the LSRM. In this paper, an indirect self-tuner is proposed for position control of the LSRM by combining the recursive least squares (RLS) estimator with the minimum-degree pole placement method (MDPP) for controller design. control system construction and operation based on one single Digital Signal Processor (DSP) are also established. Experimental results demonstrate the control scheme with on-line least-square parameter identification has a better performance than PID controller on modifying steady-error variances between each operation side in square-wave tracking. Experimental results prove that the control algorithm considering disturbances has smaller steady-state error compared with PID control algorithm. © 2011 IEEE.

For complex mechatronic systems it is convenient to modularize the system into a hierarchical structure. Especially for self-optimizing systems hierarchies can be used to reduce the complexity. Such systems have an extensive information processing, because they adapt their behavior to varying system and environment conditions in an autonomous way. In this paper we present a parametric model-order reduction based on multi-moment matching that is used to simplify hierarchical models. By this procedure the execution of a hierarchical multiobjective optimization is fastened. We compare our hierarchical approach with a multiobjective optimization of a non-reduced model for an active suspension system. A good approximation of both the Pareto sets and Pareto fronts is obtained by our approach. © 2011 IFAC.

A boiler drum BDT921 that is installed in the control Laboratory, department of mechatronics and Robotics engineering, Faculty of Electric and Electronic engineering, Universiti Tun Hussein Onn Malaysia （UTHM） is being used as a model plant to achieve the digital control system since its analog. Implementing a digital system to boiler quite a though work. This paper covers analysis from the experiment done to match with digital design that will be implemented to the real system. The digital control design will come up with the mathematical model and will be analyzed with MATLAB and SIMULINK software named as ＂Discrete Analysis ofBDT921 Simulation＂. A proportional integral and derivative （PID） controller is being chosen as the control element in discrete form as the real system is using the same control element. The output responses behave as the second order system with a bit difference in rise times and peak times compared with data obtained from experiment. With regarding to the analysis done, the digital control can be implemented and for further viewing, to be controlled digitally with computer in the control room.

A fast algorithm of solving reanalysis problem of modified linear vibration defective system was proposed based on origin shift combined approximation method. For the perturbed defective system, the generalized eigenvectors can be expressed by the combination of the basis vectors and the coefficient vectors by introducing the shift of origin parameter based on the generalized mode theory and combined approximation method. By this method, the complex operations are simplified instead of solving large scale equations. The numerical examples demonstrate that the presented algorithm is efficient and fast with good accuracy and stability.

A surface electromyogram model has been implemented with both electrical and mechanical outputs. The model has been populated with parameter values based on random distributions about experimentally observed averages. Motor unit firing rates and recruitment threshold have been defined independently for type I and type II muscle fibres. This has led to non-linear inputs to the sEMG model. The observed model outputs have been compared with experimental data. Both the electrical and mechanical outputs are shown to increase linearly with force. The rates of increase are comparable between the simulated and experimental data sets. This model is generating life-like sEMG signals and may be used to study the relationship between muscle physiology and the sEMG signal. © 2011 IEEE.

In this study, intelligent control of human eye movements system for the emotional support by a huggable pet type robot via Gaussian RBF neural network based on sliding mode control is presented. Despite active research and significant progress in the last three decades on control of human eye movements, it remains challenging issue due to its applications in prosthetic eyes and robotics. The geometry and model of human eye movements system are investigated and this system is considered as a nonlinear control system. The specified model may only be an academic exercise. It can have scientific importance in understanding of the human movement system in general. Also, it can be useful for robotics. By using Gaussian RBF Neural Networks Based on Sliding Mode control, the control goal can be achieved. The adaptation laws of designed controllers are obtained based on sliding mode control methodology without calculating the Jacobian of the system. The proposed method is capable to control of human eye movements system. Intelligent methods such as artificial neural networks are proposed to control the human eye movements and numerical simulations are presented. It is concluded that the intelligent controls applied to control of human eye movements system are emulated from the neural controls in biological system. © 2011 IEEE.

This study proposed a model based fault detection and isolation (FDI) method using multi-layer perceptron (MLP) neural network. Detection and isolation of realistic faults of an industrial gas turbine engine in steady-state conditions is mainly centered. A bank of MLP models which are obtained by nonlinear dynamic system identification is used to generate the residuals, and also simple thresholding is used for the intend of fault detection while another MLP neural network is employed to isolate the faults. The proposed FDI method was tested on a single-shaft industrial gas turbine prototype and it have been evaluated using non-linear simulations based on the real gas turbine data. A brief comparative study with other related works in the literature on this gas turbine benchmark is also provided to show the benefits of proposed FDI method. © 2011 IEEE.
