A collaborative PID and intelligent control method for a nonlinear positioning system in simulation

Despite the abundance of sophisticated tools, including advanced controllers, the Proportional-Integral-Derivative controller is still the most widely used in modern industry, controlling more than the 90% of closed-loop industrial processes. Many researchers have implemented PID controllers in pneumatic positioning systems and they all faced the problem of tuning the three different gain values. In this research project the use of a PID controller in a such highly nonlinear system is investigated. In an attempt to improve the system performance and support the classical control method´s drawbacks, an intelligent control method is implemented supplementary to a PID controller in a very modern simulation software environment. All benefits of the system behavior are recorded and illustrated in this paper, as well as comments of the significantly improved system performance.
