Road Sense Simulation Based on Sparrow Algorithm and Sliding Mode Control
In order to improve the robustness of the road sense motor output in the wire-controlled steering road sense simulation system,the steering feel torque and motor control strategy are studied.First,the dynamic differen-tial equation of the road sense feedback system is analyzed and the mathematical model of road sense torque is built by the formula of wheel correction torque.Then,an improved sliding mode control strategy based on the steering wheel angle is designed,and the parameters are optimized online using the swallow optimization algorithm.Finally,a multi-software joint simulation model is established,and the virtual simulation experiment is completed on Matlab platform to verify the robustness of the road sense feedback system.
