Abstract
Provided are a gravity search adaptive apparatus and method. The gravity search adaptive apparatus includes: a system configured to process and output a received signal; a system modeling unit configured to receive the same signal as a signal input to the system, to convert the signal using a system modeling parameter, and to output the converted signal; and an adaptive controller configured to use a gravity search adaptive algorithm to detect the system modeling parameter so that an error signal which is a difference between an output signal of the system and an output signal of the system modeling unit converges on a minimum value when the system modeling parameter is applied to the system modeling unit.
Claims18
A gravity search adaptive apparatus for modeling a system, comprising:
- a system modeling unit configured to receive the same signal as a signal input to the system, to convert the signal using a system modeling parameter, and to output the converted signal;
- and
- an adaptive controller configured to use a gravity search adaptive algorithm to detect the system modeling parameter so that an error signal which is a difference between an output signal of the system and an output signal of the system modeling unit converges on a minimum value.
A gravity search adaptive method comprising:
- calculating a system modeling parameter of a system modeling unit for minimizing an error signal which is a difference between an output signal of a system and an output signal of the system modeling unit when the same signal has been input to the system and the system modeling unit;
- and
- applying the system modeling parameter to the system modeling unit.
