This work is concerned with the extended signal quickening, a technique for manual control of higher order plants with little or no damping. It has been shown that adding first and/or higher order derivatives to the error signal and displaying the combined signal are effective in facilitating human control over such plant. This technique was first proposed by Birmingham and Taylor, and is called “Signal Quickening”. The signal quickening is further extended to incorporate future reference trajectory variation into displayed signals so as to minimize the tracking error. The design of extended signal quickening systems is based on the discrete time optimal control theory.
The experiments for a triple integrator plant with a pure time delay indicate the effectiveness of the proposed method for achieving high quality tracking. The extended signal quickening is also shown to be effective under the following realistic conditions: 1) imperfect measurement of plant state variables, 2) presence of input noise.
