Summary
This study introduces an intelligent control system using adaptive neuro-fuzzy inference system (ANFIS) to enhance vehicle stability. The ANFIS-controlled active stabilizer bars significantly reduce rollover risk and improve wheel-road interaction during steering maneuvers.
Area of Science:
- Automotive Engineering
- Control Systems
- Artificial Intelligence
Background:
- Vehicle rollover is a critical safety concern during steering maneuvers.
- Traditional anti-roll systems have limitations in actively managing vehicle dynamics.
- Intelligent control offers potential for advanced stability enhancement.
Purpose of the Study:
- To develop and evaluate an adaptive neuro-fuzzy inference system (ANFIS) for controlling active stabilizer bars.
- To demonstrate the superiority of ANFIS over PID and passive systems in preventing vehicle rollover.
- To improve vehicle stability and wheel-road interaction during dynamic steering conditions.
Main Methods:
- Implementation of an ANFIS algorithm to control active anti-roll systems.
- Training the ANFIS using carefully selected data from previous studies.
- Comparative simulation analysis against Proportional-Integral-Derivative (PID) and passive (mechanical) systems.
Main Results:
- ANFIS significantly reduced the roll angle from 8.15° to 6.87°, outperforming PID (7.08°) and passive (7.80°) systems.
- ANFIS control increased vertical wheel force from 671.06 N to 3030.40 N, enhancing stability.
- Rollover was prevented at high speeds (80-90 km/h) with ANFIS, unlike systems without active bars.
Conclusions:
- ANFIS provides a highly effective intelligent control solution for active anti-roll systems.
- The proposed ANFIS controller ensures robust vehicle rolling stability across various driving conditions.
- Active stabilizer bars managed by ANFIS offer superior performance in preventing rollover and maintaining tire contact.

In automotive engineering, car suspension systems often employ Proportional Derivative (PD) controllers to enhance performance. PD controllers are utilized to adjust the damping force in response to road conditions. A controller, acting as an amplifier with a constant gain, demonstrates proportional control, with output directly mirroring input.

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...

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...

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.

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

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,...
