The goal of this work is to develop mathematical models, stability criteria, and control designs for a two-stage poppet valve system with a simple back-side pipeline condition that may be used in a valve stack to create an independent metering function for a hydraulic circuit. First, this system is modeled as a nonlinear open-loop model as well as a linear one. The completely linear form of the flow force acting on the poppet head is derived from simplified Navier-Stokes Equations. Second, four control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov theorem to be globally asymptotically stable. The basic guidelines for selecting control gains are derived by Routh-Hurwitz method. Finally, important system parameters, especially the transient flow force and two leakages, are discussed to reveal their effects on the open-loop system stability. Simulations results illustrate that the closed-loop poppet system with either the modified PI controller or the nonlinear controller can track the desired poppet displacement represented by a sine wave with 10 HZ frequency. The LQG controller and the H [mobius] controller having fixed weighting functions or matrices are not flexible enough to satisfythe global nonlinear systems, though they exhibit the acceptable regulation behavior.

Applying And Analyzing Robust Modern Control On Uncertain Hydraulic Systems written by Brian Bax and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2006 with Electronic dissertations categories.
In this work modern robust control systems are designed and compared to standard techniques for a hydraulic implement system. The system includes an independent metering valve (IMV) and a variable displacement pump. The IMV is a powerful and versatile valve assembly. The IMV's inherent complexity makes classic control methods difficult to design. Parameter variations and unmodeled dynamics can cause sluggish performance and instability in some cases. By applying modern control, robustness can be improved relative to classical and singleinput/ single-output (SISO) control design techniques. Techniques such as H[subscript infinity] control have been proven effective in many multiple-input/multiple-output (MIMO) applications. Linear analysis shows improvement in robustness characteristics of the IMV system over a conventional PID control scheme. Nonlinear simulations show favorable system response and similarly positive robustness traits for the modern control designs.

This research explores valve design, dynamic modeling, and techniques to achieve flow control for a forced-feedback metering poppet valve system. In particular, nonlinear and linear models of a forced feedback configuration are developed and tuned through the use of root locus techniques. Typical steady state conditions as well as extreme high and low pressure drops are simulated in attempts to uncover instabilities and other possible undesirable performance characteristics of the valve. It is shown that by using a variable inlet orifice to the control volume as opposed to a constant orifice, desired system bandwidth and stability can be achieved. Open loop valve designs are then simulated with several electronic control schemes which incorporate feedback of load pressure and in some cases valve flow. An observer design is investigated as a means of providing flow feedback without additional sensor costs. Electronic flow control schemes are compared to standard mechanical pressure compensation and finally a robust analysis is provided for a chosen electronic control scheme.

Mobile Working Machines are defined by three characteristics. These machines have a cer-tain task of doing a working process, they are mobile, and they have a signifi cant energy share in their working functions. The machines should be as productive, efficient and of high quality as possible. All these machines in the fi eld of agriculture, forestry, construction, logistics, municipal sector, and in other special applications work in different applications. But, many technologies placed in the machines are the same, similar or comparable; therefore, different branches can learn from each other. Mobile Working Machines provides a wide and deep view into the technologies used in these machines. Appropriate for new engineers as well as those who wish to increase their knowledge in this field, this book brings together all the latest research and development into one place.
