Abstract

"SISTEMA DE CONTROLE PARA CONTROLAR UMA TRANSMISSãO HIDROSTáTICA". Um sistema de controle controla uma transmissão hidrostática possuindo uma bomba de deslocamento variável acionada por motor de combustão acoplada a um motor de deslocamento fixo. A bomba possui uma placa de impacto que é controlada por um sinal de controle gerado pelo sistema de controle. O sistema de controle inclui um gerador de sinal de comando de velocidade, um sensor de velocidade de motor para gerar um sinal de velocidade de motor sensoreado, um sensor de velocidade de motor de combustão para gerar um sinal de velocidade de motor de combustão, e uma unidade de controle que gera o sinal de controle como uma função da mesma. A unidade de controle gera um sinal de velocidade de motor desejado como uma função do sinal de comando de velocidade e do sinal de velocidade de motor de combustão, gera um sinal de comando de envio de alimentação como uma função do sinal de velocidade de motor desejado, gera um sinal de diferença como uma diferença entre o sinal de velocidade de motor desejado e o sinal de velocidade de motor sensoreado, gera um sinal integral pela aplicação de uma função integral ao sinal de diferença, gerando um sinal de soma como uma soma do sinal de comando de envio de alimentação e o sinal integral, e gerando o sinal de controle como uma função do sinal de soma.
