In this paper, the idea of operating an inverter to mimic a synchronous generator (SG) is motivated and developed. We call the inverters that are operated in this way synchronverters. Usingâ€¦ (More)

The paper extends quadratic optimal control theory to weakly regular linear systems, a rather broad class of infinite-dimensional systems with unbounded control and observation operators. We assumeâ€¦ (More)

We discuss the concept of a repetitive control system, and recall the main stability theorem for such systems. We give new, improved estimates on the error signal in a repetitive control system. Asâ€¦ (More)

Let A be the generator of a strongly continuous semigroup T on the Hilbert space X, and let C be a linear operator from D(A) to another Hilbert space Y (possibly unbounded with respect to X, notâ€¦ (More)

In many engineering problems, periodic signals which should be either tracked (reference signals) or rejected (disturbances) occur. A successful way of solving such problems is repetitive control, aâ€¦ (More)

Let A0 be a possibly unbounded positive operator on the Hilbert space H, which is boundedly invertible. Let C0 be a bounded operator from D(A 0 ) (with the norm â€–zâ€–1/2 = ã€ˆA0z, zã€‰) to another Hilbertâ€¦ (More)

This paper is about the state feedback regulator problem for infinite-dimensional linear systems. The plant, assumed to be an exponentially stable regular linear system, is driven by a linearâ€¦ (More)

In this paper we solve the tracking and disturbance rejection problem for infinite-dimensional linear systems, with reference and disturbance signals that are finite superpositions of sinusoids. Weâ€¦ (More)

We consider well-posed linear systems whose state trajectories satisfy áº‹ = Ax+Bu, where u is the input and A is an essentially skew-adjoint and dissipative operator on the Hilbert space X. This meansâ€¦ (More)
