Open-loop control of a plant governed by a system of differential equations in normal form is studied. The right-hand side of this system includes nonsmooth terms. The original problem is reduced to the unconstrained minimization of a nonsmooth functional. Necessary and sufficient minimum conditions...
The complete set of decoupled forms of a MIMO plant(which might be non-square and may have unstable pole-zero coincidences) achievable using open-loop precompensation is obtained in terms of certain multiplicities of the poles and zeros of. This approach, which also yields the precompensator dir...

Specify an open-loop output at the output of the plant and an input perturbation at the input of the controller.For some systems, you cannot specify the loop opening at the same location as the linearization input or output point. For example, to open the outer loop in the following system...

Stable plant poles can either be shifted by feedback, or they can be approximately cancelled by a controller. While it is known that the cancelling design impacts on the transients due to input disturbances, we show that the alternative, i.e., the shifting design, impacts on closed-loop rob...

Because the block performs an open-loop estimation experiment, do not use this block with an unstable plant or a plant with multiple integrators. To use the algorithm, you do not need an initial PID controller design. However, you must have some way to get the plant to a nominal operating...

An information system serves the parallel function of monitoring system or plant performance. The monitoring function may serve a number of purposes; specifically it may indicate values of controlled variables to guide remote control operations, warn of off-limit conditions and provide record of ...
