Manual Control System

Abstract The project deals with design and implementation of adjustment onto mounting tables in the automotive industry. Manual control system of the jigs is replaced by a pneumatic system. Advantages of the pneumatic system are eliminating service side-time, improving work flow and increasing safety and ergonomics at work. Thanks to higher effectivity of the work process, manpower can be used in other work positions.

Human Operators

This paper describes the application of a deterministic theory for characterizing or modeling the dynamics of a human operator in a manual control system. Linear time-varying, nonlinear time-varying, and non-linear constant-coefficient models are obtained by applying the theory to tracking data taken for one- and two-axis tasks with various displays. The accuracy and fidelity of these advanced models are explored in detail. Also, new information about time variability and nonlinearity of the human operator, obtained by studying the models and the manual control system signals, is presented.

System Input

The requirement for a credible monkey-man extrapolation in the area of manual control systems led to the investigation of the predictor-operator phenomenon in rhesus monkeys performing in a manual control system. Two monkeys were trained to proficiency in a single-axis visual compensatory manual control system using a random (unpredictable) system input. Data were obtained for system performance in the random case. The system input was then changed to pure sinusoidal (predictable). Data were obtained for the sinusoidal case and compared with data for the random case. Unlike humans, monkeys were not able to improve system performance in the predictable versus unpredictable case.
