FIELD: computer engineering. SUBSTANCE: device has (N-1) units which solve M differential equations, unit having MxN transparencies with constant optical density, N groups of optical splitters having MxL branches in each group, N units for calculation of minimum of Hamiltonian. Outputs of i-th unit which solves differential equations are connected to inputs of transparencies, which belong to i-th column of unit of transparencies. Outputs of these transparencies are connected to inputs of splitters of i-th group of optical splitters, output of ij-th transparency is connected to inputs of L j-th branches of i-th group, outputs of all branches of k-th subgroup of i-th groupare connected to inputs of linear photodetector of k-th unit for calculation of minimum, which belong to i-th unit for calculation of minimum of Hamiltonian. Output of photodetector is connected to input of digital-to-analog converter of this unit through serial circuit that contains adder, which additive input receives constant signal, and selector of minimal signal. Outputs of units provide output of corresponding unit for calculation of minimum of Hamiltonian. Set of outputs of units for calculation of minimum of Hamiltonian serves as device output providing two-dimensional function of optimal control effect. EFFECT: non-linear systems for automatic control. |
