The method of orthogonal projection is introduced according to the problem of feed forward parameter optimization in linear servo system with high frequency response. At first, orthogonalized basis functions are constructed and the control system is projected onto the axes of the basis functions. Then system parameters are identified along the axes of basis functions by iterative learning and high...
In order to realize the automation of sole glue working procedure, Auto-glue toe lasting machine is developed, but it is a high flexible machine and easy to produce residual vibration because of its structure. The existence of residual vibration degrades tracking precision and response speed of trajectory glue and influence the quality of trajectory glue and following procedure, this paper uses technology...
Design of networked servo control system based on CAN bus is proposed. Systematic structure of servo control system and the servo node implementation are introduced. Software hierarchical structure is analyzed in brief. Moreover, Software frame and control loop of servo node are illuminated, and especially the offset in current control loop is analyzed and the compensating method is proposed to ensure...
The application of the slide-mode observer in the sensorless vector-control of permanent magnet synchronous motor (PMSM) is proposed. Design a slide-mode observer to estimate the information of rotor position. Establish the adaptive rule and analysis the stability of the slide-mode observer. The application of the space vector pulse width modulation (SVPWM) is introduced in the control scheme of the...
