CMAC Based Motion Control of Electrohydraulic Servo Systems

Automation based electrohydraulic servo systems have a wide range of applications in nowadays industrial systems. However, they still suffer from several nonlinearities like deadband in electrohydraulic valves, hysteresis, stick-slip friction in valves and cylinders. In addition, all hydraulic system parameters have uncertainties in their values due to the change of temperature while working. This book addresses these problems by designing a suitable intelligent control system that has the ability to deal with the system nonlinearities and parameters uncertainties by a fast and online learning algorithm.
