VERDES KAIRUZ, Ramón Imad  e  GONZALEZ SANTOS, Ana Isabel. Speed control of and induction motor through MATLAB^®/Simulink^® and an OPC server. EAC [online]. 2015, vol.36, n.3, pp. 80-93. ISSN 1815-5928.

This paper shows the design of a model based predictive controller to perform a speed control of an induction motor with squirrel cage rotor with a speed reference changing through the time. To achieve this goal the software MATLAB^®/Simulink^® were used. The control is performed employing an OPC server which acts like a gateway between MATLAB^®/Simulink^® and a Programmable Logic Controller (PLC). This PLC sends the control signal to a speed driver which handles the motor. The field bus employed for the communications between the Personal Computer (PC) and the PLC was Ethernet. The designed controller is compared with an auto-tuned PID controller from the PLC OMRON^®.
