Equipment manufacturing industry is an important factor to measure a country's comprehensive national strength. The servo control technology is one of the core technologies of numerical control systems and motion control, as well as an important part of the equipment manufacturing. This paper, on the basis of motion control, studies the development status of servo control home and abroad and analyzes in-depth the various components of the AC servo control system and the parameter confirmation of the controller. It discusses the approximate processing on control system and simplification of passing functions and uses the best second-order tuning to set the project for the current loop Pl adjustment device, simplifying the current loop into an inertia link.

The hardware control system of the 5-UPS/PRPU PMT (parallel machine tool) with redundant actuation was reconstructed to realize its hybrid force/position control, which was based on the primary “IPC+PMAC motion controller” system mode. Meanwhile, more perfect open type PMT control platform was constructed. Visual Basic language was used to realize the force servo control of the redundant limb and the relevant experiment was completed in the primary CNC system, combining with the PAMC motion controller library function. The results show that the force servo control strategy is exact and the newly designed hardware control system is effective, these results also provide feasible hardware basis and control method to realize the hybrid force/position control.

3-axes motion is broadly used in industry numerical control machine. Many motion controller we use are usually limited by the number of interface it consist. But the kind of motion controller based on CAN (Controller Area Network ) can solve this problem properly. We can add a controller of one axe conveniently. I use a Advantech CAN motion controller to build the motion control system.

The chief purpose of servo control system is gap detection and control during the process of EDM. In this paper, there are evaluations and introductions about two gap detection methods--average voltage detection and effective spark number detection, which are widely used in nowadays. A new method based on fuzzy PID adaptive control about the two gap detection methods is introduced to improve the accuracy and anti-interference performance.

WEDM as a special processing method is widely used in the manufacturing. Focused on the hardware and control strategy of servo control system deficiencies, a new design plan is proposed for WEDM servo control system based on DSP. Author takes TMS320LF2407A DSP chip as core processor for the system, development of the servo feed control system. In the designing, depend on detection circuit output signal which reflect discharge gap state load, the normal spark discharge and short circuit, and be processed by the corresponding module of DSP, the principle is that get the best spark rate.

Purpose The purpose of this paper is to develop a coiling robot in the production of coated elevator compensation chains to replace the manual coiling operations and improve the quality of compensation chains. Design/methodology/approach This paper introduces both mechanical and servo control system designs of the coiling robot. The structure of two friction wheels stabilizes the conveying speed of compensation chain, so the chain speed matches with the car speed. A centering mechanism pushes the chain to its original position. Seven servo motors are integrated into the system, and they are controlled by a servo control system based on programmable logic controller, positioning controller, analog output block and touch screen. Findings The results of the project show that the coiling robot can both greatly reduce the number of workers and the intensity of the work and improve the quality of the chain. The chain lid by the robot is not only neat, but also uniform in its inner stress. Research limitations/implications When the output speed of the compensation chain from the rear friction wheel does not match the coiling speed, the coiling operation has to be halted. Then, the operator adjusts the chain speed and restarts the coiling operation. Practical implications The coiling robot is proven working. It has been adopted by a leading company manufacturing compensation chains. Originality/value This is the first coiling robot which is practically used in a production line of compensation chains. Its design, mechanism and control systems are of great reference values to people.

SUMMARYA method is described to convert information available at manipulator programming level into trajectories which are suitable for tracking by a servo control system. This process generates trajectories in real time which comply with general dynamic and kinematic constraints. Tracking accuracy will depend mainly on the acceleration demand of the nominal trajectory setpoints - the actuator output demands, in particular, must remain bounded. Our scheme takes into consideration at the trajectory computation level the dynamics of the underlying system, dynamically available information acquired through sensors, and various types of constraints, such as manipulators. It has been developed in the context of a multi-manipulator programming and control system called Kali and developed at McGill University.
