The quality of regulation criterion in an ergonomic optimization of control systems
نویسنده
چکیده
The paper discusses the problem of a machine being “sensed” by its operator. It is shown that reducing the operator’s loading with work necessary for controlling – caused by a wide use of servomechanisms – can result in deterioration of the quality of work of the human-machine system. To study this quality, the quality of regulation criterion used in automatic control engineering was chosen. It is based on the shape of the time characteristics of the operator’s response to a change in the input signal. Research was conducted to find a combination of the values of the parameters of the control system (with a hand lever as input) for which the quality of regulation is best. Those parameters were: the length of the lever arm, the operating force and the transmission ratio. By transforming the results, a dependence was found between the lever grip travel and the operating force. Their optimal values are given.

EFFECT OF LOCATION OF EXPLANATORY VARIABLE ON MONITORING POLYNOMIAL QUALITY PROFILES
The quality is typically modeled as the univariate or multivariate distribution of quality characteristic/s. In recent applications of statistical process control, quality profiles in which the relationship between a response and explanatory variable/s is captured and monitored are increasingly used to model the quality. Several techniques have been developed to enhance the speed of detecting c...
متن کاملOptimal Control Pressure for Leakage Minimization in Water Distribution Systems Using Imperialist Competitive Algorithm
One of the key factors affecting leakage in water distribution systems is network pressure management by putting Pressure Reduce Valves (PRV) in the flow path and optimal regulation of these vales in water networks. This study aimed at investigating optimal pressure management problems so as to minimize leakage in water distribution networks. To do so, an approach was proposed for both optimal ...

متن کاملISAR Image Improvement Using STFT Kernel Width Optimization Based On Minimum Entropy Criterion
Nowadays, Radar systems have many applications and radar imaging is one of the most important of these applications. Inverse Synthetic Aperture Radar (ISAR) is used to form an image from moving targets. Conventional methods use Fourier transform to retrieve Doppler information. However, because of maneuvering of the target, the Doppler spectrum becomes time-varying and the image is blurred. Joi...
