ESTIMATION STRATEGIES FOR DYNAMICAL SYSTEMS WITH EQUALITY CONSTRAINTS Conference Paper

abstract

• Constrained dynamical systems are common in spacecraft and aerospace robotics. For the class of systems subject to equality constraints, monitoring constraint violation is useful for determining the more appropriate dynamical model of the system. In this paper, two strategies for sequentially estimating the states and constraint are presented with examples. The first method constructs the constraint estimate and variance from the linearized constraint relationship and state estimates, whereas the second method directly estimates both the constraint and variance. The constraint variance is then used to calculate uncertainty bounds for determining constraint violation and subsequently selecting the appropriate system model.
