In fields such as precision manufacturing, dynamic fatigue testing, and robot collaboration, the dynamic response speed and stability of servo controllers directly determine the upper limit of equipment performance.Dailong Dynamic Servo ControllerWith core advantages such as a 0.1 millisecond measurement and control cycle and 10000Hz high-speed data acquisition, the dynamic response performance is particularly outstanding. The secret lies in the full chain technology optimization of hardware architecture, control algorithms, and signal processing, building a closed-loop system of "high-speed computation precise control real-time feedback".

The three core main control architecture is the hardware cornerstone for achieving high-speed response. The Dailong series controller adopts a three core collaborative design of DSP+FPGA+ARM, which eliminates the bottleneck of traditional single-chip computing. 32-bit floating-point DSP is responsible for real-time computation of core control algorithms, with a very short measurement and control cycle of 0.1 milliseconds to ensure instruction execution without delay; FPGA programmable devices focus on high-speed signal acquisition and processing, and can directly interface with SSI interface magnetostrictive displacement sensors to achieve 25 bit Gray code level displacement data capture; ARM is responsible for human-computer interaction and communication tasks, completing data exchange through CAN bus or DynaLive intelligent protocol to avoid occupying core computing resources. This architecture division of labor enables parallel processing of the entire process of data collection, computation, and output, providing hardware support for dynamic response.

The intelligent sliding mode control algorithm (SPIV) is the core guarantee of dynamic response accuracy. Unlike the overshoot or lag problems that traditional PID control is prone to, this algorithm can adapt to load fluctuations and environmental changes in real time through variable structure feedback control. In scenarios such as dynamic fatigue testing, precise control of various waveforms such as sine and rectangle within the range of 0.001-100Hz can be achieved. At the same time, with multi-level closed-loop tracking design, the dynamic tracking error of parameters such as force and displacement is minimized. Combined with dynamic amplitude compensation technology, it can effectively avoid waveform distortion and ensure control accuracy even in high-frequency response scenarios.

High speed signal processing and communication technology further enhance response efficiency. The Dailong controller is equipped with a 16 bit AD/DA conversion module, with a dynamic force measurement resolution of up to 30000 yards (10kHz), which can accurately capture small signal changes; A dedicated high-speed FIFO data transmission channel enables real-time uploading of data at 10000 acquisition points per second, avoiding response delays caused by data caching. In addition, the embedded DTE real-time operating system ensures timing stability when multitasking is parallel, and with the precise calibration of CaliExpress calibration software, the entire chain error from signal acquisition to instruction output is greatly compressed.

　　Dailong Dynamic Servo ControllerBy building a solid computing foundation through a three core hardware architecture, breaking through control accuracy bottlenecks with intelligent algorithms, and connecting response links through high-speed signal processing, the three work together to form the core secret of dynamic response. This technological system enables efficient and stable control in fields such as fatigue testing and precision machining, providing key support for the intelligent upgrade of equipment.
