  A disjunctive sensing and actuation problem is considered in which the
actuators and sensors are prevented from operating together over any given time
step. This problem is motivated by practical applications in the area of
spacecraft control. Assuming a linear system model with stochastic process
disturbance and measurement noise, a procedure to construct a periodic sequence
that ensures bounded states and estimation error covariance is described along
with supporting analysis results. The procedure is also extended to ensure
eventual satisfaction of probabilistic chance constraints on the state. The
proposed scheme demonstrates good performance in simulations for spacecraft
relative motion control.
