Summary
A biomimetic tail significantly improved flight stability and response speed in a flapping micro air vehicle (FMAV). This tail controller reduced response times by over 95% and enhanced flight stability during take-off maneuvers.
Area of Science:
- Robotics and Automation

Background:
- Passive stabilized flapping micro air vehicles (FMAVs) face challenges in stability and response speed.
- Biomimetic designs offer potential solutions for enhancing aerodynamic performance and control.
Purpose of the Study:
- To improve the stability and response speed of a passive stabilized double-wing FMAV.
- To investigate the effectiveness of a feedback-controlled biomimetic tail for enhanced flight control.
Main Methods:
- Developed an accurate flapping wing model for lift force calculation.
- Conducted experimental tests to determine relationships between control torque and tail parameters.
- Created a stability model for the FMAV with stabilizing sails.
- Designed a simulation controller using linearized hovering state dynamics.
Main Results:
- The flapping wing model achieved a lift force accuracy of 2.4%.
- The tail controller reduced angle and velocity response times from seconds to 0.1 seconds.
- Adjustable tail angles improved flight stability, reducing standard deviation by up to 72.96% during take-off.
- Control axis standard deviation decreased by 38.06%, confirming reduced angular deflection.
Conclusions:

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation.

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...
