LQR Control with the New Triple In-Loops Algorithm for Optimization of the Tuning Parameters

The suspension system plays a role in ensuring the stability of vehicle when traveling on road. On many modern vehicles, active has been proposed to replace conventional passive system. performance controller for depends its control method. In this paper, half dynamics model is established. Besides, LQR method also used. parameters matrix are calculated through triple in-loop optimization algorithm, which shown research. This completely novel algorithm. algorithm helps choose most optimal parameters. Thus, it ensures efficiency and controller. calculation comparison process done automatically. When loop ends, explicitly indicated. simulation MATLAB-Simulink environment. results research showed that controller, was optimized used, vehicle's oscillation significantly reduced. three survey situations, values roll angle angular acceleration sprung mass guaranteed be stable. using phenomenon “chattering” after excitation ends does not appear. topic can further developed future.
