【Abstract】 A suboptimal method for selecting optimal locations among the candidate actuator/sensor locations is developed based on the degree of observability and controllability for discrete time systems.In the approach,the candidate actuator and sensor locations contributing little to the observability and controllability are removed successively until a desired number of actuator/sensor locations is retained.This approach is simple and computationally efficient.The applications to a space truss structure demonstrate that the method is effective.更多还原
