The use of hydraulic control is rapidly growing and the objective of this book is to present a rational and well-balanced treatment of its components and systems. Coverage includes a review of applicable topics in fluid mechanisms; components encountered in hydraulic servo controlled systems; systems oriented issues and much more. Also offers practical suggestions concerning testing and limit cycle oscillation problems.A steady limit cycle amplitude is reached only when the phase lag is precisely 180Ad (see Section 10-2). ... Let us further assume the limit cycle frequency is low enough that servo- valve and motor-load dynamics contribute negligible phase ... It cannot be used effectively in troubleshooting component instabilities because of difficulties in identifying the oscillating loop and measuring the quantities involved.
