Convergence and stability of the FSR CNN model
(Institute of Electrical and Electronics Engineers, 1994)
Stability and convergency results are reported for a modified continuous-time CNN model. The signal range of the state variables is equal to the unitary interval, independently of the application. Stability and convergency ...
