The purpose of this paper is to introduce the role of a resonance control technique called a negative differential feedback (NDF) controller when the main parameters are excited on a quarter of the vehicles. This control technique is useful and effective as it helps to avoid any dangerous vibration caused during its operation. Therefore, we consider the NDF controller which plays an important role.
In addition, the robustness of natural frequency variations has been studied for the first time in a one-quarter vehicle automotive system. Multiscale homotopy (MSH) methods have been used to mathematically solve the equations of controlled systems. In the resonant case studied, Ω=2,ω= 1, calculate the actual behavior of various parameters and system behavior. The frequency response equation for controlling the amplitude of the controlled system is derived.
The simulation results were completed by MATLAB 7.0 program. The PPF controller and NDF controller are compared in the vibration system to show the best controller. Numerical results show that the NDF controller is the best in terms of eliminating oscillations and reducing amplitude values. In addition, the gain of the controller reduces the steady-state amplitude of the model in a short period of time.
In addition, the controller makes the structure more stable than other controllers. The effect of effective parameters on the controlled system is revealed. Through the obtained frequency response equations showing stable and unstable regions, the different response curves of the frame when the controller is turned off and on are plotted. Finally, the numerical results are in good agreement with the analytical results.
