Abstract
"MéTODOS DE CONTROLE AUTOMáTICO PARA UM FENÈMENO E DO FUNCIONAMENTO DE UM PNEUMáTICO E DE TESTE DE UM PNEUMáTICO, SISTEMA DE CONTATO COM O SOLO E USO DE UMA INVARIáVEL". Método de controle automático para um fenómeno do qual um parâmetro Y varia em função do parâmetro X de acordo com um curso exibindo uma subida, um extremo e uma queda, no qual o valor do parâmetro X é controlado automaticamente para manter o valor e um parâmetro Y em um valor ótimo, caracterizado pelo fato de que compreende as seguintes etapas: <sym> determinar estimativas ou medições (X~ i~, Y~ i~) para pelo menos um par "i" de valores; <sym> determinar os valores correspondentes da inclinação <244>~ i~ da linha reta passando através da origem e através de (X~ i~, Y~ i~)<sym> calcular coeficiente A~ p~ por cálculo direto ou por uma regressão a partir de um número suficiente de pares com (<244>~ i~, X~ i~), de modo a modelar uma curva de variação <244>~ i~ =f(X~ i~, A~ p~);<sym> calcular um valor alvo X~ max~ pelo uso de uma Invariável "Invt" predeterminada. Aplicação a testes e ao funcionamento do pneumático em um veículo, por exemplo, para controlar o agarramento na frenagem, com Y sendo o coeficiente de atrito e X sendo o deslizamento do pneumático sob torque.
