In this paper, a new piezoelectric stack actuator is proposed, and the modeling and simulation are completed. Generally, piezoelectric stack can take significant compressive loads but cannot tolerate tension, so this new actuator is designed that can obtain obvious bilateral actuated outputs. This actuator is made of two piezoelectric stacks and a bilateral output device. By controlling the voltage...
A general recurrent neural network (RNN) with implicit dynamics has been proposed by Zhang et al for online time-varying algebraic equations solving; namely Zhang neural network (ZNN). In this type of network systems, neural dynamics are elegantly introduced by defining a matrix-valued error-monitoring function rather than the usual norm-based scalar-valued error funtion. This makes the computational...
