MPC is a natural framework to address the issue of SA suspension control, since it facilitates optimal performances of constrained processes and is able to consider input and state constraints in the design process. If you are using MPC just for input constraints you can do away with it using LMIs (Linear Matrix Inequality). If you have neither, you simply have to use a QP solver in whatever language you are using and accept that you probably will have to do some messy coding to actually setup the numerical matrices that define the QP for an MPC problem. Note that nonconvex set constraints lead to mixed-integer problems which are difficult to solve. One of the most fundamental problems in model predictive control (MPC) is the lack of guaranteed stability and feasibility. Additional constraints (move blocking, soft & rate constraints, terminal sets, etc. These inputs, or control actions, are calculated repeatedly using a mathematical process model for the prediction.
