Esquemas de controle PID têm sido amplamente utilizados na maioria dos sistemas de controle de processos. A maioria desses processos é frequentemente tratada como sistemas de primeira ordem com tempos mortos. E também, em muitos casos, os parâmetros PID são normalmente ajustados com base nos parâmetros do processo, ou seja, a constante de tempo, o tempo morto e o ganho do processo. No entanto, uma vez que estes parâmetros de processo não podem ser obtidos com exatidão, é sabido que é difícil encontrar na prática os parâmetros PID adequados. Neste artigo, propomos um esquema de sintonia genética de parâmetros PID para sistemas de primeira ordem com grandes tempos mortos. Os autores já propuseram um método de sintonia de parâmetros PID utilizando um algoritmo genético (AG), que se baseou na relação entre o controle PID e as leis de controle de variância mínima generalizada (GMVC). Na prática, para grandes sistemas de tempo morto, pré-filtros passa-baixo de primeira ordem são frequentemente usados. O método proposto é uma versão estendida do método proposto anteriormente mencionado acima para o sistema com pré-filtro devido ao grande tempo morto, ou seja, um método de sintonia tanto dos parâmetros PID quanto do pré-filtro usando um GA. O esquema de controle proposto é avaliado numericamente em alguns exemplos de simulação.

Abstract: PID control schemes have been widely used in most of process control systems. Most of these processes are often treated as first-order systems with dead times. And also, in many cases, PID parameters are usually tuned based on the process parameters, i. e. , the time constant, the dead time and the process gain. However, since these process parameters can not be obtained exactly, it is well known that it is difficult to find the suitable PID parameters in practice. In this paper, we propose a genetic tuning scheme of PID parameters for first-order systems with large dead times. The authors have already proposed a tuning method of PID parameters using a genetic algorithm (GA), which was based on the relationship between PID control and generalized minimum variance control(GMVC) laws. In practice, for large dead time systems, first-order low pass pre-filters are often used. The proposed method is an extended version of the previously proposed method mentioned above to the system with a pre-filter due to the large dead time, i. e. , a tuning method of both PID parameters and the pre-filter using a GA. The proposed control scheme is numerically evaluated on some simulation examples.
