Struktur Dua Paras Terimbuh Tanpa Penukaran Maklumat di Antara Unit Kawalan Tempatan

Augmented two level structure without information exchange between local control unit is expended from three level structure with input-output information feed back proven to be real optimum. The advantage of this control structure is no real process output derivatives by perturbation needed. Thus control problems with undifferentiable inequality constraint G(c,y) with respect to output,y, can be easily solved. This research paper widens the usage of the control algorithms by using augmented Lagrangian function. This control structure is having two optimization loops which are external optimization loop and internal optimization loop. The external optimization loop determines optimum value of Lagrange multiplier,λ using Powell conjugate method without any derivation. The internal optimization loop determines optimum control set point, c for certain given value of λ using augmented Lagrangian method. Simulation results show that appropriate combination of the square term multipliers, (rho) and update multiplier, є could reduce the amount of optimization calculation loop for convex problems, є range from 0.9 to 1.2 is suitable for the structures. However big value of (rho) is needed to solve non-convexproblem.
