Abstract
AbstractServo pneumatic positioning system is a mechatronic approach that enables to use Pneumatic Cylinders as multi-position actuators. This technology can replace less efficient electromechanical systems in many applications. The nonlinear servo control for the pneumatic system is very important because the pneumatic system exhibits nonlinearities such as valve dead zone, compressibility of air, frictional changes, etc. The mathematical model of the servo pneumatic positioning system is derived for various physical laws and equations. The main parameters that are modeled are pressure dynamics, valve motion dynamics, mass flow rate, friction variation, and dead zone. This model is used to simulate the system behavior in Matlab-Simulink software. The paper also presents a Fuzzy PD controller design for the nonlinear servo positioning system. The designed controller performance is validated using simulation tests. From the results, it is observed that the developed controller exhibits good servo characteristics.KeywordsMathematical modelingSimulationFluid power systemsMechatronics
