Abstract This paper reports the implementation of an open architecture controller on a 3-axis machining center. This new controller, called MOSAIC-PC, takes advantage of readily available, off the shelf components, and the flexibility and low cost of the personal computer. While commercial products have been used as the building blocks for MOSAIC-PC, the overall architecture is novel. Specifically, high level CAD curves and patches, such as NURBS, can be incorporated at the machine level and sensor based machining is integrated in real-time. A description of the hardware and software components is given and the ease of integrating third party components is described. Finally the functionality of MOSAIC-PC is demonstrated.

Abstract New digital control algorithms have been developed to achieve the desired transmissibility function for a microgravity isolation system. Two approaches have been presented for the controller design in the context of a single degree of freedom system for which an electromagnet is used as the actuator. The relative displacement and the absolute acceleration of the mass have been used as feedback signals. The results from numerical studies are presented. It has been found that the resulting transmissibility is quite close to the desired function. Also, the maximum coil currents required by new algorithms are smaller than the maximum current demanded by the previously proposed phase lead/lag method.

New digital control algorithms have been developed to achieve the desired transmissibility function for a microgravity isolation system. Two approaches have been presented for the controller design in the context of a single degree of freedom system for which an attractive electromagnet is used as the actuator. The relative displacement and the absolute acceleration of the mass have been used as feedback signals. The results from numerical studies are presented. It has been found that the resulting transmissibility is quite close to the desired function. Also, the maximum coil currents required by new algorithms are smaller than the maximum current demanded by the previously proposed lead/lag method.

Performance Specifications

In this paper, an experimental procedure used efficiently and successfully for teaching in practical classes of digital control course for undergraduate students who are attending the fifth year in Industrial Electrical Engineering at Federal Institute of Education, Sciences and Technology, in Brazil, is presented. The adopted methodology is characterized by the following steps: modeling of the dynamic system to be controlled from experimental data, model-based digital controller design according to pre-established performance specifications and implementation of the designed digital controller. The experiments are performed on a data acquisition platform, in real time, based on high performance virtual/electronics instrumentation, at Laboratory of Computational Intelligence Applied to Technology. Results from an experimental activity, developed by students in the digital control course, illustrate the main practical aspects that must be taken into account in design and implementation of real time digital PI/PID control.

Purpose. Develop a methodology for the implementation of digital control systems for continuous objects on a personal computer, which should provide: bringing the temperature in the chamber to a given value at a given range of air flow in the system; maintaining the temperature in the chamber at a given level at a given range of air flow in the system; visualization and control of the stand of the thermal object; control of fan speed in order to create a disturbing effect; registration of process parameters in the thermal object. The methods. The development is carried out through the phased implementation of a digital control system for a continuous object, implemented on a personal computer. The proposed approach consists of the main stages: a controller is synthesized in a continuous form, which implements the proportional-integral-differential (PID) control law. The simulation of the obtained system is performed in the mathematical package MATLAB. At the next stage on the personal computer the software implementation of the synthesized digital regulator is executed. At the last stage, the hardware elements of the control system were developed and implemented. Findings. The use of this approach in the development of a system of automatic control of a continuous object on the basis of a thermal object allows you to effectively create a complete hardware and software part of digital SAC using Scada system Zenon. This will significantly reduce the duration and cost of commissioning of ACS in production conditions at the actual control facility. Which makes it possible to significantly reduce the duration and cost of commissioning of ACS in production conditions at the actual control facility. The originality. For the first time, a method of creating a control system for thermal objects, based on programmable logic controller with the synthesis of the system in the mathematical package MATLAB. Practical implimintation. The obtained data allow to bring the model as close as possible to the real control system and to perform effective testing of its functioning in non-production conditions.
