# Help Our Reader Control Vibration of a Suspension System

One of our LinkedIn members wrote: "I am trying to write a Matlab code for this project and am having serious problems. Actually, it is an active suspension system that has two axles, both rear and front axles, and each axle has left and right suspension mass (a full vehicle suspension system). Each suspension mass has a spring, a damper, an actuator force and a tire, and did I mentioned the tires stiffness? The assumption is that the vehicle moves at a constant speed along an even road. I wrote the differential equations. Also, I obtained the matrices.

I wrote the differential equations. Also, I obtained the matrices. There are nine inputs and 11 outputs. I wrote the matrices in Matlab but I don't know what I should do now at this step. I would be grateful if there is anyone to help me out."
