Three-axis processing of laser inner engraving machine control system can carry on multi-axis linkage control. Furthermore, it ensures multi-axis of high feeding speed and trajectory control of high precision. This article introduces the design of laser inner engraving machine movement control system. The core is a digital integrator of linear interpolation algorithm to generate the desired trajectory and control XYZ axis linkage. Wide speed range of servo motor and position detector resolution is adequate to constitute a half-closed loop drive. With integral separation algorithm being introduced in the controller, the speed of numerical control system, track speed and positioning accuracy are guaranteed in order to achieve optimal specification for dynamic and static characteristics of the whole system.

Compliant Polishing

According to the all-pervading theory, the best strategy for multiaxis compliant control system is the famous hybrid movement/force control. Until now, the typical way to get it inclines to integrate force control with movement control into one numerical control (NC) interpolator. The more axes being taken for the interpolator, the lower calculating and computerizing speed and the greater errors are. Furthermore, the errors of movement control, including the position errors and pose errors, would inevitably disturb the processing of force control for their coupling relationship. In this paper, the orthogonal movement/force servo strategy is brought forward based on the orthogonality relation of force control and movement control. Combining with the processing of aspheric surfaces polishing, the paper develops a new three-axis computer numerical control (CNC) compliant polishing method and system by the hybrid orthogonal movement/force servomechanism, in which the force controlling and movement controlling are taken in its orthogonal complement space, respectively. Experiments show that this new polishing system is of great robustness for the change of slope and curvature of the aspheric surfaces and it can polish aspheric surfaces to get ultrasmooth surfaces at nanoscale.

A mobile test system for solar collector is introduced in this paper. The mobile test system for solar collector is a flexible and convenient testing device. Its design is much more difficult than that of a fixed test system for solar collector, because it needs consideration so as to make the test system accurate, reduce the volume of the test system, ensure the stability of the test system, increase corresponding removed devices and so on. For an effective integration of the test system and a vehicle, this paper discusses a mobile platform and its control system. A movement control of the subsystem adopts ac servo system based on PC. The system takes LabVIEW which is used in a virtual instrument as the development platform. And it employs a state machine model to monitor the process of removing and taking back for the mobile platform.

Objective: determination of criteria for assessing functional reserves and reliability of voluntary movement control system under various conditions of muscular activities. Material: Students aged 17-19 and athletes aged18-27 and specialised in various sports events participated in different studies. At Physical Education classes, female students were engaged in a programme aimed at improving the reliability and reserving the control system of local and regional movements of different coordination complexity. Athletes – cyclists, wrestlers, weightlifters, shooters performed specialised movements of different coordination complexity in the process of adaptation to specific physical loads in each sports event. The quality of motor regulation demonstrated by cyclists, weightlifters and wrestlers was analysed according to muscular activities, intermuscular relationships during muscular performance manifestation in the process of cyclic and acyclic loads, whereas shooters performed it according to the result of shooting at a target. Results: It has been revealed that in the process of a long-term adaptation to various types of muscular activities, the reserves of the movement control system representing different coordination structure are characterized by: an increase in the power of compensatory rearrangements to maintain the motor function reliability in complicated conditions of motor regulation and, in particular, during functional deprivation of the key sensory systems, maximum activation of physiological systems in the process of muscular activity and compensated phase of developed fatigue. The most prominent changes occur in movements, in the control of which the highest levels of regulation are involved. In movements regulated at lower motor levels, the shifts are less significant. Such movements are more stable, programmatic and harder subjected to change by means of physical exercises. Conclusions: The key criteria for the reserve capacities of the movement control system are as follows: power, efficiency and interchangeability of compensatory responses and mechanisms ensuring the reliability of movement control under the influence of distorting factors and fatigue; speed of transition to programme mechanism of motor regulation in the process of improvement under stable functioning conditions; manifestation of the "afferentation narrowing" principle in the sensory control of movements under stable functioning conditions.
