The performance of a controlled system depends on the location of the control actuator, in addition to the controller itself. Thus actuator placement is part of controller design for these systems. In this paper, a number of different actuator placem

This paper is concerned with the use of $\BBH_{2}$ -control performance metrics in finding optimal actuator locations for a class of infinite-dimensional systems. Conditions that guarantee convergence of the optimal actuator location for the finite-d

Although synthesis of H ∞ controllers via solution of algebraic Riccati equations (AREs) has been known for several decades, there is not a generally accepted algorithm that is suitable for large-scale systems. However, systems of large model order

The performance of a controlled distributed parameter system is known to be dependent on the location of the control actuator, in addition to the controller itself. Thus actuator placement should be part of controller design for these systems. In thi

In control of distributed parameter systems, there is usually freedom on where to place the actuators. The actuator location should be chosen to optimize the performance objectives and regarded as part of the controller design. In this paper, H∞-pe
