Title: Method for regulation of dynamic objects
Inventor: KULIKOV G G
IPC: G05B15/00
Filed: 1995-10-10
Granted: 1998-07-27
Abstract: 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
