Elara Aerospace's Trust Vector Control (TVC) software
To compile the C code into a shared library:
gcc -shared -o tvc_hardware.so -fPIC tvc_hardware.cLet's break this down into steps:
- Define the basic structure
- Create the main Python script
- Develop C modules for low-level hardware control
- Implement the control algorithm
- Add telemetry and logging
The are the important files containing the TVC software code:
tvc_controller.py: The main Python script.tvc_hardware.c: The C module for low-level hardware control. This will be compiled into a shared library that our Python script can use.tvc_hardware.so(on Linux/macOS) ortvc_hardware.dll(on Windows): Compiled C shared library.tvc_log.txt: Log file.
These names clearly indicate the purpose of each file and follow common naming conventions in software development. The prefix tvc_ helps identify all files related to the Thrust Vector Control system.
This basic structure provides a foundation for the TVC software. Here's what each part does:
- The Python script defines the main control loop and high-level logic.
- The C module handles low-level hardware interactions for better performance.
- The
TVCControllerclass manages the control algorithm, including target angle, current angle, and PID gains. - The control loop runs at 100 Hz, constantly adjusting the TVC based on the difference between target and current angles.
- Logging is implemented to track the system's behavior over time.
To improve this system, consider:
- Implementing full PID control instead of just proportional control.
- Adding error handling and system health checks.
- Implementing a communication protocol to receive commands from a ground station.
- Adding more sophisticated modeling of rocket dynamics.
- Implementing sensor fusion if multiple sensors are available.
