Unbalanced mechanical systems are always of great concern to engineers because of, the implications on the reliability of the systems. This paper presents two approaches to handling the problem in mechanical systems equipped with electrical motors driven by variable speed drivers. The two methods are able to verify the imbalance of the system based on the cyclic load factor (CLF) and on the discrete Fourier transform (DFT), both using the torque signal obtained from the drive. Algorithms were developed to obtain the necessary parameters from the drive and then converted into ladder programs able to be embedded in the drivers so that real time balancing control can be achieved. Experimental results demonstrate the possibility of assisting the balancing of mechanical systems based on the developed algorithms. Among the advantages of maintaining a balanced system using the present approach is preventing equipment wear, increasing the useful life and reducing maintenance costs.

The new requirements of modern real-time distributed supervision and control systems such as more flexibility, interoperability, and cost savings, have motivated the use of software-intensive solutions both in academia and industry. Following this trend we have presented, in a previous publication, the design rationale and implementation issues of a flexible and reusable software platform (ARCOS) that relies on the CORBA component model (CCM/CIAO), the DAIS (data acquisition from industrial systems) standard, and framework technologies. This paper builds on this previous publication by presenting a new assembly tool that allows for the visual component-based implementation of ARCOS-based systems and the automatic generation of the related CCM/CIAO/ARCOS artifacts. To demonstrate the power of such a tool, two example applications are presented.
