چکیده
Objective functions for sensor selection are investigated in linear time-invariant systems with a large number of candidates. This study compared the performance sets obtained using three types D-optimality-based indices as objective based on greedy method. The computed snapshot-to-snapshot Fisher information matrix, observability Gramian and Kalman filter-based matrix. Both random eigenmodes considered, selecting best-performing set each identified, well computational complexity corresponding wall clock times. optimized index works best that index, expected. We also clarified trend selected by method function terms other function.

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

This paper presents a methodology for design of instrumentation sensor networks in non-linear chemical plants. The method utilizes a robust extended Kalman filter approach to provide an efficient dynamic data reconciliation. A weighted objective function has been introduced to enable the designer to incorporate each individual process variable with its own operational importance. To enhance...
متن کاملDistributed Kalman Filter in a Network of Linear Dynamical Systems
This paper is concerned with the problem of distributed Kalman filtering in a network of interconnected subsystems with distributed control protocols. We consider networks, which can be either homogeneous or heterogeneous, of linear time-invariant subsystems, given in the state-space form. We propose a distributed Kalman filtering scheme for this setup. The proposed method provides, at each nod...

متن کاملOn Controllability and Observability of Fuzzy Dynamical Matrix Lyapunov Systems
We provide a way to combine matrix Lyapunov systems with fuzzy rules to form a new fuzzy system called fuzzy dynamical matrix Lyapunov system, which can be regarded as a new approach to intelligent control. First, we study the controllability property of the fuzzy dynamical matrix Lyapunov system and provide a sufficient condition for its controllability with the use of fuzzy rule base. The sig...
