시뮬레이션 중간에 s-function을 초기화(clear mex) 할 수 있나요?
Mostrar comentarios más antiguos
안녕하세요.
clear mex; 함수를 이용하면 c 코드로 이루어진 s-function의 모든 변수가 초기화되는 것으로 알고 있습니다.
시뮬레이션 중간에 시스템이 down되는 상황을 구현하고 싶습니다.
시뮬레이션 시작과 끝 사이에 s-funciton을 초기화할 수 있는 방법이 있을까요?
감사합니다.

I understand that you want to simulate a system failure and want to re-initialize S-function in middle of simulation.
To initialize the S-function in the middle of the simulation, you can follow these steps:
- Define a flag or condition within the S-function to indicate the reset state. For example, you can use a boolean variable like isReset and initialize it to false.
- In your simulation loop or control logic, when you want to simulate a system failure and reset the S-function, set the reset flag to true. This can be done using an appropriate trigger or condition.
- In the S-function's “mdlInitializeSizes” or ”mdlInitializeConditions” function, check the value of the reset flag. If it is true, reset the necessary variables or parameters to their initial values.
- Ensure that the reset flag is reset to false after the initialization is complete. This can be done within the S-function's “mdlStart” or “mdlOutputs” function, depending on your specific requirements.
By following these steps, you can reset and initialize the S-function between the simulation start and end, simulate a system failure and restart the S-function in a clean state.
Please note that the implementation details may vary depending on your specific S-function code and simulation requirements.
