A real-time method is presented to adoptively estimate three-dimensional unmodeled external torques acting on a spacecraft. This is accomplished by forcing the tracking error dynamics to follow the Lyapunov function underlying the feedback control law. For the case where the external torque is...

Structural classification and parameter estimation (SCPE) methods have been used for studying single-input single. output (SISO) parallel and feedback nonlinear system models from input-output (I-O) measurements. The uniqueness of the I-O mappings of different models and parameter uniqueness of...

This paper demonstrates the utility of systems and control theory in the analysis of economic systems. Two applications demonstrate how the analysis of simple dynamic models sheds light on important practical problems. The first problem considers the design of a retail laboratory, where the...

There is great interest in the application of technological solutions driven by a thriving CRM industry. It has been shown the more effective the implementation of SFA, the greater its impact on increased sales performance. Previous research on SFA adoption has focused on the individual as the...

This dissertation includes two essays on adverse selection and moral hazard problems in reinsurance markets. The first essay builds a competitive principal-agent model that considers adverse selection and moral hazard jointly, and characterizes graphically various forms of separating Nash...

This dissertation considers three topics in professional advising and forecasting. Chapter 1 examines a principal's optimal contracting with experts. In an environment where experts have heterogeneous private signal distributions and type dependent reservation utilities, we show that the...

Local labor markets are characterized by rigidities in their patterns of adjustment to short-run fluctuations. With or without unions, fluctuations in employment, hours worked, and money wages are unlike the patterns predicted by conventional discrete-exchange labor-market theories. Moreover...
