Our non-feathered friends: sensing and control in insect-scale flight
… of insect-scale flight. The method builds a linear state-space model from a quasi-impulse response of an aeroelastic system. Second, we seek to better understand possible tradeoffs associated with aerodynamic force production and gyroscopic sensing in insects. In particular, we look at how …

New Multi-Phase Diode Rectifier Average Models for AC and DC Power System Studies
… small signal model for system-level study using linear control theory. A new average modeling approach for three-phase and nine-phase diode rectifiers with improved ac and dc dynamics is proposed in this dissertation. The key assumption is to model the load current using its first-order Taylor …

Analytical Modeling of a Heaving Wave Energy Converter
… Given evidence of successful application of control theory to approximating wave interactions, a linear control theory-based model of a simplified heaving device is proposed, with the necessary wave theory background discussed in detail. The implementation of the model in MATLAB and the …

Active Flight Path Control for an Induced Spin Flight Termination System
In this thesis, we describe a method for controlling the cycle-averaged velocity direction of a fixed-wing aircraft in an unpowered, helical descent. While the aircraft propulsion system is disabled, either intentionally or due to a failure, the aerodynamic control surfaces (aileron, elevator, and …

Improved continuous-time higher harmonic control using H [infinity] methods
… and also increases its operational cost. Passive control techniques have been applied to helicopter vibration suppression, but these methods are generally heavy and are not robust to changes in operating conditions. Feedback control offers the advantages of robustness and potentially higher …

Adaptive control of nonlinear discrete-time systems and its application to control of a flexible-link manipulator
… work are to develop direct and indirect adaptive control strategies for discrete-time nonlinear systems and to investigate the applicability of the proposed schemes to adaptive tracking control of a flexible-link manipulator. The first problem considered is indirect adaptive control of a fully as …

Optimal nonlinear control and estimation using global domain linearization
… teaches that intelligence rests on feedback control. Thus, there are discrete symbols and continuous sensory-motor signals. Sensorimotor dynamics are well-represented by nonlinear differential equations. A possible construction of symbols could be based on equilibria. Language is a symbol …
