The design and implementation of analog filter structures for real-world sensory applications can be a challenging process, due to the typical interdependence of sensor units, analogue filter elements and digital processing devices. Therefore, most design approaches still rely on a prototypic filter implementation and a subsequent measurement- based validation. This paper discusses a Hardware-in-the-Loop (HIL) based approach for analog signal processing elements, based on circuit modelling and simulation and the integration of an adequate hardware interface. The adequacy of the novel approach is evaluated for a weighing application based on strain gauges and provides a proof of the suggested procedure. The achieved results based on a case study for weighing systems shows the adequacy of the approach for real sensor applications.

This paper is purely a model to determine the design circuit to implement Partial Discharge (PD) detection in FPGA technology. The research shall involve ISE Simulator version 10.1i (Xilinx) and ISE Xilinx Synthesized Technology (XST) using Very high integrated circuit Hardware Description Language (VHDL) programming to evaluate the use of Field Programming Gate Array (FPGA) for the detection and counting of partial discharge signals in high voltage underground cable. The impulse signals at the input data have very fast rise time in the range of 1 ns to 2 ns. The output signals of peak detector block, 64 bit BCD counter with reset block and reset automatic block is processed using reset automatic block and 64 bit latch block for keep output data in LCD to constant when the 64 bit BCD counter block is reset and return to zero again until update new data again. The combination of all blocks of PD detection circuit system is tested by using ISE simulator. In the next stage, this method will be implemented on a lab simulation scale for testing and validation. © 2010 ieeE.

A modelling study on pneumatic cylinder actuator systems is carried out based on the standard orifice theory. The pneumatic cylinder actuators are modelled as a cascade connection of two nonlinear subsystems affine in the control input. The model validation has been conducted by comparing open-loop system dynamical responses obtained through simulation and experiments. Finally, a class of robust servocontrol strategy is proposed, which guarantees the profile following precision. An example is included to demonstrate the servocontrol design procedure.

There are now a range of advanced simulation tools available which facilitate the modelling and analysis of complex systems. At the ABB ALSTOM POWER Technology Centre, the control Group have been utilising the versatility of two such products to model and simulate complex industrial power plant. The potential benefits include improvements in the plant design, control system design and in process operation. This paper will describe two industrial case studies where the specialised power plant simulation tool ACSL/MMS has been used in conjunction with MATLAB/SIMULINK to model, analyse and undertake control design studies on power plant.

Proceedings of the 1998 iee colloquium on Power Electronic systems simulation

作者： Clare, J.C. Summer, M. Butt, D. Palethorpe, B. Univ of Nottingham Nottingham United Kingdom

The need for combined power electronic circuit and control loop simulation was explored. The desirable characteristics of a computer aided design package were defined and the capabilities of two popular packages were compared. The SIMULINK package is most convenient for control structure development using simplified models of the power electronic system. However, the Saber package is more powerful when the interactions between the power electronic circuit topology and the control loop must be studied in detail. Such a model allows the development of control code virtually to the point where the algorithms can be directly transferred to the target hardware.

Proceedings of the 1998 iee colloquium on The Use of systems Analysis and modelling Tools: Experiences and Applications

作者： Bozin, A.S. Cambridge Control Ltd Cambridge United Kingdom

The Power system Blockset (PSB) is a modern design tool based on SIMULINK that allows users to rapidly and easily simulate power systems. The electrical systems built with the blockset can be connected to other systems to investigate the interactions between them. PSB is compatible with all of the MATLAB application toolboxes and blocksets, and it can be integrated with the STATEFLOW to model and simulate complex reactive systems. It is completely extensible and can be used as a starting point for the creation of additional starting blocks.

Proceedings of the 1998 iee colloquium on Open control in the Process and Manufacturing Industries

作者： Bass, Julian M. Univ of Hertfordshire Herts United Kingdom

The design of embedded systems requires strict adherence to stringent safety, reliability and temporal constraints. A simplified model of the embedded system development process is presented. The model emphasizes the role of simulation and modeling to produce executable specifications of the system under development. Executable specifications provide the basis for automatic code generation. This collection of techniques provides early feedback on the quality of design decisions and reduces development lead-times enabling allocation of greater effort for analysis and testing. Co-simulation is seen as desirable to enable resolution of conflicting trade-offs modeled using specialist notations.

作者： Bates, I.D. Chester, E.G. Kinniment, D.J. Newcastle EPSRC Engineering Design Cent

Programmable Logic controllers (PLCs) are commonly used in the implementation of industrial control systems. Statecharts are a suitable tool for the specification of complex reactive control systems. Statemate produced by iLogix Inc. enables the design, validation and simulation of a statechart model. The authors have previously developed a methodology and supporting software to enable the targeting of PLCs from a Statemate statechart model. This paper describes a case study which has been undertaken to verify the correct operation of the methodology and software tool.

iee colloquium on simulation in Medicine (Ref. No. 1998/526)

作者： J.J. Ross D.G. Mason I.G. Paterson D.A. Linkens N.D. Edwards University Department of Anaesthesia Northern General Hospital Sheffield UK Department Automatic Control & Systems Engineering University of Sheffield UK

The authors' previous work has demonstrated self-learning fuzzy control as a powerful, flexible and versatile control technique which adapts itself easily to changing patient conditions. It has never previously been applied to multiple input/output parameter controllers in medicine. The authors are investigating this technique for providing automated control of drug infusions supporting the cardiovascular and renal systems of patients in 'septic shock'. To construct the control system the authors are using this stratagem: modelling the shocked patient; verification of the model; validation of the model; controller strategy development in simulation using the validated model; physical control system development; clinical trials. Here, the authors highlight their validation techniques.
