Developed an expert system of an empirical method to choose correct expressions for PID controllers tuning in open loop

The aim of this paper is describe the methodology followed for the expert model development based on rules, for a expert system orientated to the PID controllers design for open loop systems. It starts with a brief introduction of the PID controllers design for open loop systems, followed by the organization of the existing rules, and the explanation of a new way to obtain specific rules to choose between the different expressions to optimize a defined specification in the final application phase of expressions to obtain the values of the parameters.
