Stability and control refer to the ability of a system, such as an aircraft or vehicle, to maintain its desired position and orientation. Stability ensures that the system returns to its original state after a disturbance, while control involves the mechanisms used to adjust and guide the system's movements. In engineering, stability can be influenced by factors like design, weight distribution, and external forces. Control systems, such as feedback loops and actuators, help manage these factors to achieve smooth and predictable performance, ensuring safety and efficiency in operation.
