Exact linearization for applications in industrial pneumatics

In this article the method of exact linearization is applied to pneumatic systems. These systems are used in industrial environments like in glassworks or automotive industry to guarantee an exact and constant air flow. In addition with a subordinate high dynamic pressure control the closed loop reaches the desired setpoint as soon as possible. Although in the transformed system model zero dynamics exists, a unique transformation could be found that guarantee a stable substitute model. All inaccuracies causes static deviation are compensated by the controller without the use of any integral gain. Special learning cycles which are known from other industrial applications are not required to tune the designed controller. With respect to the limited computing power of industrial hardware the presented algorithm is optimal designed for low execution time and source consumption.
