Automation is “the application of machines to tasks once performed by human beings, or increasingly, to tasks that would otherwise be impossible”, Encyclopaedia Britannica [1]. The term automation itself was coined in the 1940s at the Ford Motor Company. The idea of automating processes and systems started many years earlier than this as part of the agricultural and industrial revolutions of th...

The progress of semiconductor technology and control systems the last years has made possible the realisation of highly efficient and low priced microprocessor-based controllers for the control of asynchronous motors. This paper describes the design and realization of a microcomputer-based device for frequency regulation of an asynchronous motor. Through the regulation of motor’s supply frequen...

Received Jan 30, 2014 Revised Mar 2, 2014 Accepted Mar 18, 2014 In this paper, experimental results of 3-phase permanent magnet synchronous motor (PMSM) sensorless speed control are presented. To estimate the rotor position, a sliding mode current observer (SMCO) was implemented. This observer estimates the back emfs of the motor in the stationary reference frame using only the measured voltage...

Abstract Aristek Highpolymer is a company that produces emulsion polymers and synthetic resins. In the production process, R301 agitator has often experienced overheating, which disrupted process caused damage to mixer engine motor. Currently, checking temperature on Agitator been done manually using thermo-gun information be hampered several times stirrer motor go off. For this reason, study d...

This paper discusses the preliminary development of a neural network-based process monitor and off-line controller for abrasive flow machining of automotive engine intake manifolds. The process is only observable indirectly, yet the time at which machining achieves the specified air flow rate must be estimated accurately. A neural network model is used to estimate when the process has achieved ...

Toyota Motor Corporation is arguably the most successful automotive company in the world, outperforming its US competitors on many fronts, including product quality and engineering productivity. Prior research on Toyota’s product development practice has revealed a number of striking differences with those of US automakers; however, from a design process standpoint, the differences are relative...

A local volatility model is enhanced by the possibility of a single jump to default. The jump has a hazard rate that is the product of the stock price raised to a prespecified negative power and a deterministic function of time. The empirical work uses a power of −1.5. It is shown how one may simultaneously recover from the prices of credit default swap contracts and equity option prices both t...
