A Fuzzy Optimal Control Model

Optimal control is a very important fleld of study not only in theory but in applications, and stochastic optimal control is also a signiflcant branch of research in theory and applications. Based on the concept of fuzzy process, a fuzzy optimal control problem presented. Applying Bellman’s Principle of Optimality, the principle of optimality for fuzzy optimal control is derived, and then a fundamental result called the equation of optimality is given in fuzzy optimal control. Finally, as an application, by using the equation of optimality, a portfolio selection model is solved. c
