摘要

This article is concerned with the problem of mean-square stability and stabilization under an energy harvesting sensor, where the sensor can harvest energy from the external environment. When the sensor's energy is insufficient to maintain regular communication between the sensor and the controller, the sampled data packets are regarded as missing. Otherwise, they can be successfully transmitted in the communication network. To address this problem, we first establish a continuous-time modeling framework for a class of randomly sampled systems with an energy harvesting sensor. Then, a corresponding discrete-time stochastic model is constructed. By establishing the equivalence between the continuous-time and resulting discrete-time systems, a stabilizing controller is designed to guarantee the mean-square stability of randomly sampled systems. In particular, the limit of the probability of successfully transmitting sampled packets is derived, which plays a critical role in the equivalence analysis of systems, as well as the controller design. Finally, a practical example is provided to demonstrate the effectiveness of the proposed controller design strategy, where both energy-harvesting-constrained and energy-harvesting-constraint-free scenarios are illustrated.
