# bellman equation paper

The main difference between optimal control of linear systems and nonlinear systems lies in that the latter often requires solving the nonlinear Hamilton–Jacobi–Bellman (HJB) equation instead of the Riccati equation (Abu-Khalaf and Lewis, 2005, Al-Tamimi et … Path Dependent PDEs. ). Initially, the system is assumed to have no faulty components, i.e. (2006) Linear forward-backward stochastic differential equations with random coefficients. A neces- Example 1.

In the design of control systems for industrial applications, it is important to achieve a certain level of fault tolerance.

Given any realization , , and , , the following equality holds irrespective of strategy , The proof follows from equations ( (2019) A Weak Martingale Approach to Linear-Quadratic McKean–Vlasov Stochastic Control Problems. ∎. Proceedings of IEEE International Midwest Symposium on Circuits and Systems, 2018. Three courses of action are defined to troubleshoot the faulty system: (i) let the system operate with faulty components; (ii) inspect the system, and (iii) repair the system.
