摘要:

The state regulation of single-input systems with unmeasurable polynomial disturbances is considered using dynamic output feedback. A simple solution involving a rank test of a matrix of Markov parameters is presented to this problem, and to a dual problem of output regulation of single-output systems.

摘要:

The approximate solution of systems governed by linear differential operators in two space dimensions is achieved by a new least-squares collocation technique using Patterson quadrature points and weights. Boundary conditions which are identicaly imposed on the approximate solution may be optimised, and the scheme may be used to rapidly predict feedforward control parameters. Boundary conditions which cannot be imposed on the approximation are also considered. The technique is applied to a short-forehearth heat-conditioning green glass, and its use in the online control of such a process is discussed

摘要:

The basic assumption from implicit self-tuning theory is that, for self tuning to occur, the control input obtained from the estimated system model converges to the value whic would be obtained if the system parameters were known. As as direct result of this, only certain control strategies are acceptable. Here a general rule for the self-tuning property of pole-placement self tuners is obtained, and previous strategies are shown to be special cases of this.
