| Abstract |
The availability of highly-integrated and powerful microelectronic components enables advantageous drive concepts and new problem solutions to be realized in servo drive technology as well as others. In particular, the large computing capacity of the new RISC and DSP processors allows digitalization to be considered for high-speed regulating circuits, which until now had been built using analogue technology. The powerful CPU's in conjunction with ASIC technology allow complex control and regulating functions to be concentrated into the smallest package. This contribution describes a motor regulation concept combining in one unit the functions of a positioning control system and all regulator cascades of a servo controller. This concentration is made possible by consequent digitalization of all control and regulating functlons. The field coordinate regulator as used permits synchronous motors as well as asynchronous induction motors to be used as controlled units. In the area of converters the new power electrlc components allow improvements towards greater
power ratings with shorter switching times. The motor regulator concept presented here contains a large number of interfaces. This takes into account anticipated future needs for interlinkage capability to form extensive automation systems. |
