| Abstract |
The on-line implementation of highly sophisticated control laws for variable-speed drives often lead to a capacity overflow of the used microprocessors. Although the use of a control automaton in order to take over a part of the microprocessor tasks is not a new technique, but the fact is that these circuits which employed TTL logic devices were cumbersome and were fixed within a determinated structure. Because of their high degree of integrability and the possibility of software reconfiguration, the LCA (Logic Cell Array) revive the interest in the study of this structure. For this reason, we propose throughout this study, a completely revised organisation of a control automaton of a speed drive for synchronous or asynchronous motors fed by a PWM voltage inverter. The behaviour of the automaton is analysed by means of simulation. |
