This simulator is a graphical environment where the user can easily carry out the tasks of modeling, simulation, optimization, parameter estimation, and data reconciliation, among others. Several publications validate the growing importance of the EMSO software. COCO simulator, Ascend, etc.) and it has been developed as free software by the ALSOC Project, which is financed by the Brazilian Government and certain private and public institutions. The EMSO ( Environment for Modeling, Simulation, and Optimization) can be considered as a good option among those of free access (e.g. Such companies put simulators on the market at higher prices, and most of the times, inaccessible for mid-range and small-range domestic enterprises, public higher education institutions, and new research groups. The development of reliable and powerful process simulators, with good databases and ease of communication is mainly carried out by private and foreign enterprises. Palabras clave: Simulador EMSO, control de procesos, herramientas educacionales, controladores PID y PBSM. El modelo obtenido fue utilizado en el diseño de controladores PID y PBSM, los cuales fueros probados ante saltos de set point y una trayectoria de set point impuesta. Para la supervisión de las variables del proceso se utilizó un modelo en SIMULINK conectado al proceso a través de comunicación OPC. Keywords: EMSO simulator, process control, educational tools, PID and PBSM controllers.Įste trabajo ilustra un procedimiento de modelado y control de procesos de nivel y flujo usando el simulador EMSO acoplado al proceso con un PLC SIMATIC S7-200 como interfaz de comunicación OPC entre la instrumentación del proceso y el sistema de cómputo del controlador. The model obtained was used in the design of controllers PID and PBSM, which were tested for step disturbances of the set point and an imposed set point trajectory. In order to supervise the variables, a SIMULINK model was connected to a laboratory process module through OPC communication. It uses the EMSO simulator to connect to a process by means of a SIMATIC S7-200 PLC as interface for the communication between the process instrumentation and the controller computing system. This work shows a procedure for modeling and control of level and flow processes.
