State Feedback Control Design of Cars Wings in Order to Improve Road-Holding on Corners of Roads

Car wing has many capabilities to work on and benefit from. There are different types of wings and spoilers in sport cars that are being used to help having better acceleration, braking, etc. Generally after aerodynamic analysis of wings or rear spoilers, and simulation the second step is to find the best control system to achieve maximum advantages from wings and spoilers. In other words, the wing working time is during car’s cornering and turning on different angels, braking or accelerating that is the time for a control system to operate. In this paper the goal is to implement state feedback tracking control system and optimization of the system by LQR method around equilibrium and operating points of the system specially during cornering of the vehicle. So to obtain the goal, the first step is to review previous works and benefit from. Then the second section is considered for mathematical calculation and the system dynamics plus design of mechanical components and assembled system by CATIA software. After that the control model is extracted for the control system. Furthermore the control system, which is tracking control system, is designed, implemented and the results are shown by figures and plots. The final step is to optimize the control system by LQR optimal control method and the results are compared to other methods. In this article the control system is simulated by MATLAB software.
