This paper proposes the use of cylinders as primary invariant sets to be used in certain state-constrained control designs. Following the idea originally introduced by O'Dell, the primary invariant set is intersected with the state constraints to yie

We consider the problem of controlling a group of vehicles to a formation. The approach mimics the development of dynamics of a system of particles subject to constraints. In particular, we use the notion of constraint forces to achieve and maintain

This paper presents the application of a discrete adaptive observer (DAO) to an IBM head/disk assembly system. Because of the difficulties in tuning, a genetic algorithm is implemented off-line to obtain optimal observer parameters for the DAO. Simul

A control profile is generated which suppresses one or more resonant dynamics in a flexible dynamic system. This control profile can be used as a velocity profile, or as a shape filter to an arbitrary control command. The robustness can be arbitraril

A control profile is generated which suppresses all the resonant dynamics in a hard disk drive flexible arm. This control profile has both the drive voltage and velocity constraints which are required in hard disk drive long seek control. The control

This paper proposes the parallel observer system (POS), a multirate estimation technique for discrete time systems, to compensate for systems whose output measurements are only periodically available and under the presence of matched and unmatched un

This paper proposes the adaptive parallel observer system (APOS), a multirate estimation technique for discrete time systems, to compensate for output measurements that are available only periodically and for systems whose frequency content is beyond

This note focuses on linear discrete-time systems controlled using a quantized input computed from quantized measurements. Nominally stabilizing, but otherwise arbitrary, state feedback gains could result in limit cycling or nonzero equilibrium point

A piezoelectric tube actuator is employed as a sample positioning device in Nanocut, a cutting instrument conceived to study the mechanics of nanometric cutting. Extension of functionality of the instrument as a nanometric machine tool motivates the

Abiotic stresses reduce plant productivity. We focus on gene expression analysis following exposure of plants to high salinity, using salt-shock experiments to mimic stresses that affect hydration and ion homeostasis. The approach includes parallel m
