Optimal Control Theory | PDF Today we will cover discrete time control and the bellman equations continuous time control and the hamilton jacobi bellman equations an important special case: linear quadratic gaussian and linear quadratic regulator problems. In the first five chapters of this book, we treated in considerable detail linear control theory for continuous time systems. in this chapter we give a con densed review of the same theory for discrete time systems.

Principle of optimality: if b – c is the initial segment of the optimal path from b – f, then c – f is the terminal segment of this path. in practice: carry out backwards in time. need to solve for all “successor” states first. recursion needs solution for all possible next states. doable for finite/discrete state spaces (e.g., grids). Optimal control law: (cont.) definition for discrete linear regulator systems for linear tracking systems for minimum fuel control of first order plant for minimum time control: double integrator plant second order plant with real poles for minimum time energy control of first order plant for minimum time fuel control: double integrator plant. Most optimal control problems do not have closed form solutions. one exception is lqr case.

Most optimal control problems do not have closed form solutions. one exception is lqr case. If there are no constraints on the states or on the control variables, and if the initial and final times are fixed, a general continuous time optimal control problem can be defined:. Optimal control in continuous space and time contains many complications related to the existence, uniqueness and smoothness of the solution, particular in the absence of noise. This is the discrete time riccati equation (dre). In this chapter, after introducing the dynamic programing, we will show how this optimal decision making tool can be used to solve discrete time optimal control problems.
