Opportunity-Awaiting Control----One new study field in stochastic control theory

The essence of opportunity-awaiting control is to give up some part of control chances to improve control precision. It is a new practical direction in stochastic control field. In this paper, the description of its cost functions is given, then its two elementary problems consisting of consistency of the cost functions and design of control strategy are discussed. Taking rectangular target as an example, a solution for opportunity-awaiting control is provided based on the theory of satisfactory control^[1]and LMI approach.
