Servo Rapid Prototyping and Validation Solution

The development of modern guided and maneuvering vehicles places unprecedented demands on servo performance. As a key actuator in the control system, the servo converts control signals into mechanical movement, generating the required torque to manipulate subsystems and control the maneuvering and attitude of the vehicle. The dynamic response, control accuracy, and reliability of the servo directly impact the overall performance of the vehicle, determining its maneuverability and guidance precision. Therefore, servo system design must not only satisfy complex mechanical and electrical constraints but also enable rapid validation and iterative development to meet the high-efficiency requirements of modern aerospace R&D.

The Servo Rapid Prototyping and Validation Solution is built on the SIVB simulation test system integration platform, providing full digital simulation, rapid control prototyping, and hardware-in-the-loop (HIL) testing capabilities. It enables simulation of control algorithms, implementation of control circuits, hardware board testing, and evaluation and optimization of transmission system performance. The system uses modular modeling to include servo circuits, servo motors, motor drivers, reduction gear mechanisms, and nonlinear factors such as friction and backlash, allowing designers to rapidly validate, design, integrate, and verify servo performance within a virtual environment.

This system offers high real-time performance, with a CPU simulation step as short as 50 μs and a single-channel servo control cycle ≤0.2 ms, supporting four servo loops simultaneously. Users can send frequency sweep, step, loaded and unloaded angular velocity commands to the servo while collecting power voltage/current, signal voltage/current, servo angle feedback, and control angle data for comprehensive performance analysis. The system also supports automatic generation of target control code and loading into the real-time simulation computer, integrating software verification with hardware testing.

Equipped with a reflective memory interface, the solution enables distributed co-simulation with other prototyping systems, such as the flight control rapid prototyping system, supporting multi-system collaborative development and testing. It also supports a wide range of signal simulation boards (PWM, DA, AD, DIO, RS422/485) and user hardware (motors, transmission devices, load simulators), fulfilling servo performance verification under various operational conditions.

Functionally, the system provides a graphical human-machine interface for rapid test development and configuration, supports automatic generation, loading, and execution of test cases, and performs performance testing of servos and components. It includes real-time data acquisition, processing, analysis, and plotting. The system can form a closed-loop control with real servos, execute servo commands from data acquisition nodes, and interface with flight control simulation systems to validate servo responses to flight control commands.

This solution is widely applicable to servo design, development, and validation organizations, enabling functional verification, interface testing, and performance analysis during the servo R&D phase. It significantly enhances development efficiency and system reliability, providing strong technical support for the rapid development of modern aerospace and guided weapon servos.
