This paper develops a novel formulation for quality of service (QoS) aware networked observer and PI/PID controller
design in the presence of specified rate of random packet dropouts. We here derive the stability conditions for the controller and
observer gains using asynchronous dynamical system (ADS) formulation of the networked control system (NCS) in discrete time which
yields a set of linear matrix inequalities (LMIs). The control design has been validated on two test-bench energy systems viz. battery
with DC/DC converter and synchronous generator with power system stabilizer. Numerical simulations report the joint observer and
controller’s performance in the presence of random packet drops within output feedback control scheme using PI/PID controllers and
employing state estimation for the battery and synchronous generator systems. The major numerical challenge includes handling
nonconvex constraints in LMIs and stabilizing the observer-based controller with specified rate of packet dropouts. Monte Carlo
simulations are provided to compare the uncertain state trajectories, state estimation errors and control efforts under different
probability of packet dropouts for the two test-bench energy systems.
