The hydraulic independent metering is an advanced actuator driving technique that allows the implementation of advanced control algorithms or methods. The main concept of independent metering is to control hydraulic actuators ports, which are the meter-in and meter-out, separately. In this article, a novel stepped rotary type valve has been developed for embedding in hydraulic independent metering systems, instead of conventional types such as poppet and spool. The insertion leads to developing different and novel control techniques, which require software-in-the-loop simulation and hardware-in-the-loop simulation of the proposed system. The paper explores the dynamic representation of this valve and defines its own performance limitations. This includes the development of a linear model comprising its two main subparts which are the stepper motor and the rotary orifice. Consequently, the linear time-invariant methods are used to explore the performance of the valve by considering the effect of different parameters namely the pressure drop, friction coefficient, damping coefficient, and bristle coefficient.

“…the electromagnetic force of the stepper motor due to the armature speed and the effect of displacement during the various mode operations [12]. Another study demonstrated more advance model by adding electromechanical resonances simulation which may decrease the performance due to the vibrations, stalling, or losing steps [13,14]. In [9], a dynamic stepping motor model it was also proposed to combine with nonlinear dynamic Modular High Temperature Reactor (MHTGR).…”

“…In [13,14], the model was used for the stepper motor control system and the parameter identification purposes only, not used for the online condition monitoring with the capability to identify symptom of faults or component degradations. Furthermore, the previous stepper motor based CRDM in PWR [12], has not considered the condition monitoring.…”

Control Rod Drive Mechanism (CRDM) based on stepping motor is one of the components applied in High Temperature Gas Coold Reactor (HTGR) to control the reactivity as well as to maintain the safety of reactor. The stepping motor requires a unique condition monitoring to avoid any failures especially due to the specific environments of CRDM in HTGR such as the allowable of high temperature, high radiation and the location of stepper motor inside a pressure shell. This research aims to demonstrate an online non-invasive condition monitoring method without direct access to the CRDM of HTGR based on voltage and stator current measurements. A simple stepping motor CRDM simulator is employed. The online condition monitoring is carried out by direct pattern matching of the output signals of logic generator block and the output signals of motor driver. The online method utilizes signature patterns of voltage and stator current signals of the healthy motor as a baseline for healthy motor. In addition, the method is applied to detect highresistance problem on the connector between the motor driver block and the stepper motor to show the effectiveness and the applicability of this method. The online condition monitoring system demonstrates a capability to identify a minimum detectable simulated high-resistance for about 2.9% which decreases the measured stator current and motor's torque for around 5.1% and 3.3%, respectively. The paper also points out signatures of healthy motor, including mutual inductions of the motor's winding in voltage and current measurement which can be used as the fault symptom indicators for online monitoring purposes.
