The paper introduces the concept of a filtering controller (FC), which uses sliding mode control as its basis. The FC ‘seamlessly’ integrates a smoothed variable structure filter with a variable structure controller. The paper provides the concep

A scheme for an electrohydraulic vibrator excited by a two-dimensional valve is proposed, which significantly extends the frequency range compared to that of vibrators excited by conventional servo valves. In the two-dimensional valve, the rotary mot

This paper describes the development and evaluation of a fault detection strategy for a high performance hydrostatic actuation system, the electrohydraulic actuator (EHA). The approach makes use of the extended Kalman filter (EKF) technique for param

In this paper, a neural network based control system is proposed for fine control of intake air/fuel ratio in a bi-fuel engine. This control system is an add-on module for an existing vehicle manufacturer's Electronic Control Unit (ECU). Typically th

A pressure-compensated valve (PC valve) is a type of flow control device that is a combination of a control orifice and a compensator (often called a hydrostat). The compensator orifice modulates its opening to maintain a constant pressure drop acros

In digital valves, stepper motors are often used as the electro-to-mechanical interface. To sustain both high speed of response and good quantitative accuracy, a special algorithm has been designed to control the stepper motor to produce a continuous

The electrical-mechanical interfaces of servo valves and proportional valves display electromagnetic nonlinearities, such as hysteresis and saturation. In many cases, these nonlinearities have usually unfavorable effects on the performance of the who

In hydraulic servo systems, a pilot stage is often used to reduce the influence of Bernoulli’s forces and frictional forces when trying to accurately position a spool. A unique pilot controlled valve (defined as a two dimensional or “2D” flow c

The control of hydraulic servo-systems has been the focus of intense research over the past decades. The highly non-linear behaviour of these devices makes them ideal subjects for applying different types of sophisticated controllers. This paper cons

An experimental approach of using a neural network model to identifying a nonlinear non-pressure-compensated flow valve is described in this paper. The conjugate gradient method with Polak-Ribiere formula is applied to train the neural network to app
