An l1-optimal linear time-invariant (LTI) compensator may have an order signiΓΏcantly higher than that of the plant. In the state feedback case, there has been recent work exploring the use of nonlinear static feedback controllers which provide near optimal performance. In the case of D12 square and

β¦ Synopsis
In this paper, the performance of discrete time periodically time-varying controllers for rejection of lp speciΓΏc and uniform disturbances is analyzed. For control of linear time-invariant plants, this paper distinguishes linear time-invariant controllers from linear non-time-invariant periodic controllers in the performance analysis. For a given linear non-time-invariant periodic controller, a linear time-invariant controller is constructed and necessary and su cient conditions are presented under which the linear time-invariant controller gives strictly better l p control than the non-time-invariant periodic controller.

Consider a linear plant with a strictly proper rational transfer function and an input which is a known periodic waveform of unknown amplitude and phase. In the case when the periodic waveform has inΓΏnitely many non-zero harmonics, it is pointed out that for a wide class of linear, time-invariant (i
Extremely low-frequency (ELF) magnetic field exposure systems are usually subject to field disturbances induced by external sources. Here, a method for designing a feedback control system for cancelling the effect of external ELF magnetic field disturbances on the magnetic field over the exposure ar
The issue of rejecting periodic disturbances arises in various applications dealing with rotating machinery. A novel adaptive feedforward controller (AFC) design method for rejecting periodic disturbance is proposed. It can be added to an existing feedback control system without altering the origina
