The present application relates to a kind of variable stiffness fiber reinforced programmable soft actuator unit, including flexible matrix and controllable module, flexible matrix is pipeline-like, and controllable module is fixed on the outer layer of flexible matrix distribution;Controllable module uses single-layer module or the multi-layer module arranged inside and outside;Each layer of controllable module is wound by at least one variable stiffness fiber according to certain angle and direction;The control line of connection controllable module is distributed in the inner cavity of flexible matrix, and is connected with external control system;The two ends of the inner cavity of flexible matrix are blocked and leave medium filling and discharging mouth, and fluid medium is filled in the inner cavity;Controllable module state is two kinds of flexible state and rigid state, when carrying out the deformation control of soft actuator unit, by controlling part variable stiffness fiber to be rigid state, another part variable stiffness fiber is flexible state, realizes the deformation control of soft actuator unit.

The invention discloses a solar array simulator and a method for improving its dynamic performance, which relates to the field of programmable power supply. In a simulation mode, a voltage control loop is shielded, an output terminal voltage feedback signal is sampled, and an IV curve current programming reference value is obtained by looking up a table with the output terminal voltage as an index, and the output of the IV curve is completed with a current control loop. In order to increase the output operating point switching speed, a differential feedback signal of the dynamic change of the output terminal voltage is added to the current control loop to improve the dynamic adjustment performance of the simulator, and a voltage clamping circuit is combined with an FPGA programming control method to limit the feedback amount of the dynamic change of the voltage, so as to ensure the loop stability and effectively improve the dynamic response performance of the simulator when switching between different operating points.
