METHOD FOR REGULATION OF DYNAMIC OBJECTS Russian patent published in 1998 - IPC

FIELD: automatic control of output coordinate of dynamic objects. SUBSTANCE: stochastic regulator is introduced into control circuit in order to take into account random fluctuations of environment and object characteristics. Method involves generation of linear array of constants X={x} which length is M and which covers complete range of output coordinate values x, and linear array of control actions U={u} which length is N. Then method involves generation of two- dimensional array of transition probabilities P= {p} which size is NxM. Each element P jk of this array represents estimation of probability of transition of controlled object from state {x k} during i-th control step to control objective, i.e. state at control step (i+1), if control action u j has been applied at i-th step. Values of probabilistic estimations P are detected by analysis of a priori statistic data about operations of this instance of dynamic object. Then i-th control step uses output coordinate x(t i) for choice of value k which conforms to condition and generation of control action U(t_i+1) = U_j, using Monte Carlo method. Then this control action is applied to controlled object. Value of probabilistic estimation P jk is updated at step (i+1) using recurrent equation P_jk(t_i+1) = λP_jk(t_i)+(1-λ)A(t_i+1), where (t_i+1)=1 for and A(t_i+1) = 0 otherwise, λ is a priori constant. These operations are repeated during each control step. EFFECT: increased dynamic precision of regulation of output coordinate of complex dynamic objects in steady-state condition. 1 dwg
