Summary:

In rocketry competitions, such as the International Rocket Engineering Competition (IREC), unguided sounding rockets are the most commonly used, relying solely on aerodynamic stability to make necessary trajectory corrections during flight. However, this approach has limitations since these vehicles lack mechanisms to ensure apogee accuracy. The active control of a sounding rocket involves methods for orienting and stabilizing the vehicle during flight, using inertial sensors, GPS, and aerodynamic surfaces. These systems allow continuous trajectory and stability adjustments by processing real-time data. In this context, this work proposes the development of a PID-based attitude control system, aligned with IREC guidelines, to improve the accuracy of rocket apogee. For the PID controller design, the second method of the Ziegler-Nichols rule was adopted, based on a linearized transfer function, to calculate the control loop gains. Gain Scheduling technique was employed to estimate gains under different flight conditions. These gains were integrated into a nonlinear six-degree-of-freedom simulator, allowing Monte Carlo simulations to assess the controller's robustness. Several parameters were considered to evaluate the controller's efficiency, including energy efficiency, accuracy, and data dispersion. The designed PID controller demonstrated low actuator effort, indicating good energy efficiency, along with high accuracy and low dispersion concerning the desired apogee
