Optimal control systems is a branch of mathematics that determines how to control a dynamic system over time to optimize an objective function. The goal is to find control signals that satisfy physical constraints while maximizing or minimizing a performance criterion. 
Optimal control systems have many applications in science, engineering, and operations research. The theory also applies to many management science and economics problems that involve systems evolving over time. 
Optimal control systems involve determining control and state trajectories for a dynamic system over a period of time. The Model Predictive Control (MPC) technique uses a system model to predict future plant outputs. 

Optimal control problems can be classified into three types:
The simplest problem
Two-point performance problem
General problem with the movable ends of the integral curve
