Crane payloads are frequently subject to oscillations induced through movement and external disturbances. These oscillations degrade performance and can be dangerous. Input shaping is an effective method to move cranes without creating oscillation, however it is not effective on initial swing. This paper develops a feedback control system, with two operation modes based on input shaping, that a...

In multiperiod control one sequentially chooses the value of an input variable to keep an output variable close to a target value. At any stage the input variable has to be such that the output is close to target while at the same time it provides as much information as possible about the model that relates input and output, to help keep the output close to target in the future. Certainty equiv...

Steady-state dynamic simulation of a variable reluctance stepping motor is carried out by applying two different excitation voltages. First a single-step voltage is applied to the motor, and a sinusoidal voltage, as the first term of Fourier series of the single-step voltage, is then used as the input voltage of the motor. In both cases plots of machine torque, current and speed are presented. ...

This paper presents a novel adaptive control methodology for a class of uncertain nonlinear systems in the presence of unmodelled dynamics. The adaptive controller ensures uniformly bounded transient response for system’s both input and output signals simultaneously. The performance bounds can be systematically improved by increasing the adaptation gain.
