The invention relates to an
adaptive learning control method of a piezoelectric ceramics driver. The
adaptive learning control method of the piezoelectric ceramics driver comprises the following steps of (1), building a dynamic hysteretic model of the piezoelectric ceramics driver and designing a control method with the
artificial neural network and a PID combined, (2), adopting a
reinforcement learning algorithm to achieve adaptive setting of PID parameters on line, (3), adopting a three-layer
radial basis function network to approach a strategic function of an
actuator in the
reinforcement learning algorithm and a value function of an evaluator in the
reinforcement learning algorithm; (4), inputting a
system error, an error first-order difference and an error second-order difference through a first layer of the
radial basis function network, (5), achieving mapping of the
system state to the three PID parameters through the
actuator in the
reinforcement learning algorithm, and (6), judging the output of the
actuator and generating an
error signal through the evaluator in the
reinforcement learning algorithm, and updating
system parameters through the
signal. The
adaptive learning control method of the piezoelectric ceramics driver solves the
hysteresis nonlinear problem of the piezoelectric ceramics driver, improves the repeated locating accuracy of a piezoelectric ceramics drive platform, and eliminates influence on a system from
hysteresis nonlinearity of piezoelectric ceramics.
