Motor Control as the Control of Perception
Perceptual and Motor Skills, 2013This paper describes a test of Perceptual Control Theory (PCT), which views motor control as part of a process of controlling perceptual inputs rather than motor outputs. Sixteen undergraduate students ( M age = 19.9 yr.) were asked to control one of three different perceptual aspects of an animated display—a shape, a motion or a sequence—using the ...

The control of d-c motors was one of the first electronic-control projects. Recent developments, particularly the fully automatic and co-ordinated control of the armature power circuit and the field power circuit, have greatly increased the acceptability of these controls for industrial use. This paper describes the control functions associated with an

We investigated the possible influence of automatic word reading on processes of visuo-motor transformation. Subjects reached and grasped an object on which the following Italian words were printed: "VICINO" (near) or "LONTAN" (far) on an object either near or far from the agent (experiments 1, 2); PICCOLO (small) or "GRANDE" (large) on either a small ...

One of the challenges when considering the motor control of birdsong is to understand how such a wide variety of temporally and spectrally diverse vocalizations are learned and produced. A better understanding of central neural processing, together with direct endoscopic observations and physiological studies of peripheral motor function during singing,

The vestibular system is an essential sensory system that generates motor reflexes that are crucial for our daily activities, including stabilizing the visual axis of gaze and maintaining head and body posture. In addition, the vestibular system provides us with our sense of movement and orientation relative to space and serves a vital role in ensuring

Abstract An algorithm for computing robust sets of pulse timing for stepping motors that will follow arbitrary but predetermined trajectories is presented. The algorithm uses simulated feedback control and pole assigment techniques to compute the desired torque.

International Review of Neurobiology, 1999
Publisher Summary This chapter describes three sensory-to-motor reflexes and their associated central circuits and synapses. The uniquely identifiable neurons comprising these reflex circuits offer an excellent opportunity for investigating detailed molecular mechanisms underlying the development and operation of the central nervous system (CNS ...

IEEE Transactions on Control Systems Technology, 1997
This paper deals with the control of induction motors. First we show that field-oriented control can be simplified by considering the modulus square of the flux, namely F=f/sup 2/=/spl phi//sub a//sup 2/+/spl phi//sub b//sup 2/ instead of f. Second, we perform an input-output linearizing control without using any of Lie derivatives.

Control systems for d.c. traction motors are well established. The developments in power converters, particularly GTO thyristors and IGBTs, and the use of microprocessor controllers have produced control systems which offer a wide and flexible control range with efficient power conversion, whilst utilising relatively simple control techniques. The main
