Bancada Didática de Controle de Levitação Magnética Edibon RYC CLM

A Unidade de Ensino Controlada por Computador para o Estudo de Regulação e Controle, “RYC”, permite que os alunos simulem um sistema integrador, um sistema de primeira ordem e um sistema de segunda ordem e os regulem com um controlador PID ou compensador Lead & Lag. A unidade também permite simular perturbações e compensações para analisar a resposta do sistema.

Uma ampla gama de aplicações: Módulo Servo Motor DC, Módulo Bola e Feixe, etc. para trabalhar com a unidade “RYC” estão disponíveis para estudar uma resposta real dos sistemas de controle para complementar o Estudo de regulação e controle em tempo real.

Esta Unidade Controlada por Computador é fornecida com o Sistema de Controle de Computador EDIBON (SCADA) e inclui: A própria unidade + uma Caixa de Interface de Controle + uma Placa de Aquisição de Dados + Pacotes de Software de Controle de Computador, Aquisição de Dados e Gerenciamento de Dados, para controlar o processo e todos parâmetros envolvidos no processo.

RYC-CLM. Magnetic Levitation Control Module.

The “RYC-CLM” Magnetic Levitation Control module has been designed to study a practical control

system.

The “RYC-CLM” module consists of two main components: the “RYC-CLM” apparatus and the “RYCCLM” interface box. The “RYC-CLM” apparatus contains all the sensors and actuators such as electromagnet, current sensor, position sensor, etc. The “RYC-CLM” interface box contains all necessary

components for power supplying, signal conditioning, etc.

The components are used in conjunction with the “RYC” unit to control the vertical position of the

metallic ball through the control of the feeding current of the electromagnet.

The system allows to insert disturbances manually
