Servo system is widely used in aerospace, weapons, shipbuilding, industrial automation and other fields. With the development trend of servo system exchange, digitization and integration, it is particularly important to improve the development efficiency of servo system. The traditional servo system development and design mainly consists of four stages: demand analysis, design, implementation, and test verification. Each stage is relatively independent, and may introduce more design defects in the early stages. It requires iterative design and will inevitably improve the development of the servo system. Cycle and cost. Using Model Based Design (MBD) servo system design verification process solutions can greatly improve the development efficiency and effectively reduce costs.
solution
The servo system design verification process solution integrates the four mutually exclusive stages in the traditional development process, starting from the requirements analysis stage to verify and test, allowing engineers to devote their energies to the study of algorithms and test cases. , Let the computer complete the automatic generation of embedded real-time C code, speed up the starting efficiency of software and hardware. The development process of the servo system MBD is shown in the following figure:
The MBD method provides four key elements in the development of the servo control system: object modeling, controller analysis and synthesis, object and controller simulation, and controller product integration.
The model is a unified description of the controlled object and the control system. It is designed through mathematical simulation, and the system model is continuously improved in each stage to ensure the consistency of the work in each stage. Model-based design can quickly complete design iterations, and complete algorithm models can be implemented with automated code generation products. As a result, model-based design can reduce design errors, reduce costs, and reduce rework.
