The growing demand for positioning accuracy in machines with high speed plays an important role in achieving high productivity gain. A system that is capable to achieve both coarse (macro) and fine (micro) positioning finds a variety of applications in precision positioning. In the proposed work, a macro positioning stage is developed with a ball screw actuator and a micro positioning stage is developed with an additional gear reduction unit. The coarse and fine positioning with friction compensation is achieved and the steady state error is minimized. The developed system is controlled using a programmable logic controller and operated with human machine interface.
... This depends on several factors such as space constraints, maintenance requirements and available power sources. Mechatronic Actuators (MA) have an advantage over Hydraulic Actuators (HA) with respect to maintainability, cost and safety (Edward, 2009 andMuhammad, 2012). This makes them highly desirable in systems with these considerations. ...
Mechatronic systems are used as control and drive units in many engineering applications from space technology to robot arms. The main drive units of mechatronic actuator systems are the DC motors. The selection of motor to be used in the systems is an important task in projects. The most suitable motor, which answers the requirements of the project, should be selected. In this article, the studies in the scope of selecting the motor for the mechatronic actuator system of a given capacity are disclosed. Unlike the related studies in literature, in this study Design of Experiment (DoE) method is used. 2k factorial methods have been used as a DoE method. With 2k factorial methods fewer tests conducted according to the full factorial method that uses combinations of all inputs and selection of most suitable motor for the requirements is succeeded.

Main focus of this paper is control of electromechanical actuator (EMA) for aerospace applications. Control of EMA done using position regulator and control which combine position and speed regulator is shown. The main guideline is to decrease power losses, heating and current consumption in the system. One of the important areas within the field of variable speed motor drives are the system's operational boundaries. Presently, the operational boundaries of variable speed motor drives are set based on the operational boundaries of single speed motors, i.e. by limiting current and power to rated values. This results in under-utilization of the system, and places the motor at risk of excessive power losses. In this paper, the first part represents general concept of electromechanical actuators and mathematical modelling of the system; then the control of position and speed of electromechanical actuator (EMA) by using PID controller is presented. The second part shows simulations of our own design of control speed and position by PID controller using SIMULINK and MATLAB software.

Experimental research on the 2D full span model in the supersonic indraft tunnel, which includes over three hundred tunnel runs, are presented. Variable geometric parameters were: nozzle shadow area, obstacle-nozzle wall angle, obstacle-nozzle gap and nozzle area ratio. In its conclusion, the paper discusses results and presents some suggestions for the future research.
A model is proposed to calculate load distribution over threads of planetary roller screw mechanism (PRSM) with pitch deviation. Firstly, four kinds of machining errors of threads including pitch deviation, deviation of thread angle, division error of multiple threads and deviation of pitch diameter are analyzed, and the relationships among them are investigated. After analyzing the relationships among the errors, pitch deviation is chosen to be the main machining error to investigate because it can reflect the effects of other machining errors, and is the most influential machining error on the contact condition and deformation compatibility relationship, i.e. the load distribution of PRSM. Based on the proposed model, the effects of pitch deviation on the load distribution of PRSM are studied through numerical analyses, and load distributions under different machining precisions are analyzed. In order to experimentally verify the investigation, two PRSM samples are measured and tested under the same experimental conditions. The experimental results show that load distributions over threads will fluctuate because of the existence of pitch deviations. The pitch deviations, load distributions over threads and wear depths of threads in the samples show obvious accordance, which indirectly demonstrates the effects of pitch deviation on load distribution.
A novel method for precision position control of ball screw actuator system with dual positioning range (coarse and fine) is presented in this paper. The automatic positioning of the system is achieved using programmable logic controller. The static and dynamic frictions of the actuator system are identified with Tustin and LuGre friction models. The positioning of developed actuator stage is achieved with micrometer accuracy with single ball screw actuator, where a special gearing mechanism is used to reduce the speed of the servo motor. Better positioning is achieved with friction compensation.
The paper proposes an open end winding PMSM based electromechanical actuator for altitude control through Thrust Vector Control. The open end winding configuration with single dc source has the inherent advantage of applying the voltage directly to the phase thus enabling reduced voltage operation. The paper presents the modeling and hardware implementation of the Open end winding PMSM and its drive. The closed loop position control is also carried out to validate the performance of the proposed scheme. The modeling and the simulation study is carried out in MATLAB/SIMULINK. The performance of the proposed system is evaluated through simulation and experimental results.
