The open loop system means the output of the system is free from their input. In the closed-loop system, the desired output depends on their input. The open loop system is called the non-feedback system while the closed loop is the feedback system. The control and controlled process are the two components of the open loop system.

This paper focuses on the design of a nonlinear model predictive control (NMPC) scheme for a cement grinding circuit, i.e., a ball mill in closed loop with an air classifier. The multivariable controller uses two mass fractions as controlled variables, and the input flow rate and the classifier selectivity as manipulated variables.

Once the input passes into the start of the system and produces the output, the motor initiates the movement of the crosshead or the ram accordingly. The main difference between an open-loop system and a closed-loop system is that the closed-loop system has the ability to self-correct while the open-loop system doesn't.
