Abstract

In this research the active suspension system of railway wheelset system is presented. The purpose of this research is to design active suspension system for a solidaxle railway vehicle using linear quadratic regulator (LQR) method. The objective of Linear quadratic regulator (LQR) is to minimize the lateral displacement and its yaw angle of the wheelsets. This method to improve the performance of the vehicle in terms its lateral displacement and yaw angle when the vehicle moves on a straight and curve tracks. Performance of this system has been compared with the passive suspension system. The input to the system is track irregularities, the radius curve with 1500m and angle with 7°. The results show that the curving performance in active suspension system is better than passive suspension system. System has been implement by performing computer simulations using the MATLAB and SIMULINK toolbox.
