The invention discloses an evolvable hardware controller, comprising a reconfigurable hardware. The reconfigurable hardware comprises a plurality of processors which are mutually connected by network; the processors are internally provided with hardware equipment control modules including hardware equipment control programs and memorizers of main control program modules including main control programs of genetic algorithm; the main control programs operates the genetic algorithm on the processors in sequence; the main control program modules further comprise communication units which communicate with each processor through the network and transmit the operation right of the main control programs in the processors in sequence; the hardware equipment control modules further receive the order of the main control programs in the each processor and return to an executing state; the main control programs adopt the genetic algorithm and control the hardware equipment by the means of the hardware equipment control programs; and only one processor has the operating right of the main control programs at any time. The invention has the high reliability and still can continuously execute control task even if some processors or network connection go wrong.
