This paper develops a novel predictive position control (PPC) based on inverse system method for fast response and high-performance operation which is applied to the active magnetic bearing (AMB) flywheel system. Due to the simplicity and lower-order of decoupling model based on inverse system control (ISC) method, the proposed controller could combine deadbeat and direct predictive control (DPC) expediently. Its performance is compared to conventional PID position control and PID-ISC. Simulation results have demonstrated modified characteristics including faster positon response, no parameter tuning and adjustable current constraints.
