摘要： A cascaded synchronized system includes a nonlinear transmitter, a nonlinear cascaded receiver, a phase-detector/controller coupled to the receiver, and a signal generator also coupled to the receiver. The transmitter is responsive to an externally generated transmitter forcing signal for producing and transmitting a chaotic communications signal containing phase information. The cascaded receiver is responsive to a receiver forcing signal and to the chaotic communications signal for producing a chaotic receiver output signal containing phase information. The phase-detector/controller is responsive to the chaotic communications signal and to the receiver output signal for producing a correction signal. The signal generator is responsive to the correction signal for producing the receiver forcing signal in phase with and having the same frequency as the transmitter forcing signal.

摘要： A control system for tracking the operation of a nonlinear system has two parts: a tracking subsystem and a controlling subsystem. The tracking subsystem generates a parametric signal and the controlling subsystem controls and stabilizes the nonlinear system operating under operating conditions corresponding to that parametric signal. The controlling subsystem includes a modulator responsive to the parametric signal and to a feedback signal for producing and applying an input signal to the nonlinear system to cause the nonlinear system to produce an output signal. The controlling subsystem also includes means responsive to the output signal for producing the feedback signal. The controlling subsystem also includes correcting means, operable when the time average of the feedback signal is substantially nonzero, for bringing the time average of the feedback signal from a substantially nonzero value to a substantially zero value, and maintaining means, operable when the time average of the feedback signal is substantially zero, for maintaining the time average of the feedback signal over the selected period of time at a substantially zero value.

摘要： A cascaded synchronized nonlinear system includes a nonlinear transmitter having stable first and second subparts. The first subpart produces a first transmitter signal for driving the second subpart and the second subpart produces a second transmitter signal for driving the first subpart. The nonlinear transmitter transmits the second transmitter signal to a nonlinear cascaded receiver. The receiver, being for producing an output signal in synchronization with the second transmitter signal, includes a first stage (a duplicate of the first subpart) responsive to the second transmitter signal for producing a first receiver signal. The receiver further includes a second stage (a duplicate of the second subpart) responsive to the first receiver signal for producing the output signal. The cascaded synchronized nonlinear system can be used in an information transfer system. The transmitter, responsive to an information signal produces a drive signal for transmission to the receiver. An error detector compares the drive signal and the output signal produced by the receiver to produce an error signal indicative of the information contained in the information signal.
