Continuous-time low-gain integral control strategies are presented for tracking of constant reference signals for finite-dimensional, continuous-time, asymptotically stable, single-input single-output, linear systems subject to a globally Lipschitz and non-decreasing input nonlinearity and a locally Lipschitz, non-decreasing and affinely sector-bounded output nonlinearity.
Local exponential rotor speed and flux modulus tracking are achieved for any constant reference value and for restricted time-varying reference signals; any known motor parameters values (including constant load torque) and any initial condition, including rotor speed and fluxes, belonging to an explicitly computed domain of attraction are allowed.
We address the constrained output tracking of constant references for linear parameter-varying systems.
For the case of constant references, we propose a control scheme which minimizes a quadratic cost function.
There is surely a more fitting description for someone who makes constant reference, as he did again last week, to "dreamworlds", "illusions" and "fantasies".
A negative control mouse injected with luciferin was placed next to treated animals during each image acquisition to provide a constant reference for the background.
Secondly, a constructive procedure is proposed for the design of closed-loop switching signals for SBNs to track a constant reference signal.
Based on the algebraic expression of BCNs and by constructing a series of reachable sets, a general procedure is proposed for the design of the state feedback laws for BCNs to track a constant reference signal.
In this sense, a crucial role is played by information on health and the health care system, and by investments into outcomes research to make these tools a constant reference point for decision making by physicians and people in charge for developing health care policies.
