	abstract = {A family of hybrid control algorithms is developed that steer a nonholonomic autonomous vehicle to the source of a scalar signal present in the environment. In an idealized setting, we develop a general hybrid control scheme that globally asymptotically stabilizes the vehicle position about the source. Pursuing a practical implementation, a series of perturbations to the family of controllers is introduced, resulting in a semiglobal practical stability of the vehicle position about the source. An example of a recently developed conjugate direction-based controller ?tting into this family is developed and demonstrated by simulation and experiment.},

	abstract = {We consider the problem of steering a nonholonomic vehicle to the source of a radiation-like signal with only measurements of the signal. We propose a general control strategy for vehicle steering which is based on an optimization algorithm for minimization of nonlinear functions without gradient information. We state the main properties of the strategy and specialize it to the control of nonholonomic vehicles. We discuss its implementation in a hybrid controller which coordinates vehicle steering and logic elements. We present global convergence and stability results for the closed-loop system. We also discuss two possible modifications to our algorithm that improve its performance when applied to real-world environments.},

	abstract = {<p>We consider the problem of steering an autonomous vehicle to locate a radiation source utilizing measurements of the radiation intensity only. We propose a control algorithm that locates the source through a sequence of line minimizations of the radiation intensity. We implement in a hybrid controller, with sample-and-hold and logic variables, a discretized version of the algorithm suitable for steering a point-mass vehicle. The algorithm confers global convergence and practical stability properties to the closed-loop hybrid system. We discuss these properties and characterize the region of convergence for the vehicle. Convergence and stability results are supplemented with simulations.</p>},
