Optimal Sensor/Actuator Location for Descriptor Systems using Lyapunov-Like Equations
Résumé
A method for optimal sensor and actuator location is proposed for the linear time-invariant descriptor systems. The actuators and sensors are selected to maximize the energy transmitted from the inputs to the state variables and from the state variables to the outputs respectively. Since controllability and observability can be quantified by the corresponding gramians, the problem of optimal actuator and sensor location is linked to the maximization of the gramians. Due to the finiteness of the possible locations for actuators and sensor this problem can be efficiently solved using integer optimization tools. An illustrative example is provided.
