Abstract:
1. An adaptive system for solenoid control to achieve low impact landing with latching, with variable initial energy, and with variable path drift, comprising: (a) sense means, for obtaining parameters indicating the state of a controlled solenoid, said state comprising a magnetic state; (b) path memory means, for retrieval of predetermined information descriptive of possible low-impact landing paths in the state space of said controlled solenoid said information comprising information descriptive of magnetic state; (c) a variable path number, associated with said information from said path memory means, differentiating said landing paths with respect to initial energy; (d) a variable path drift parameter, associated with said information from said path memory means, differentiating said landing paths with respect to pattern of drift along among said landing paths; (e) path number determination means, for comparing said information from said path memory means with said parameters from said sense means, thereby establishing a defined path number associated with said parameters from said sense means; (f) loss parameter setting means, setting said variable path drift parameter; (g) magnetic error evaluation means, determining an error between said magnetic state of said controlled solenoid as obtained by said sense means and a magnetic state from said path memory means, corresponding to said defined path and said path drift parameter; and (h) drive control means, responsive to said magnetic error evaluation means and setting an output signal controlling the flow of electrical energy into said controlled solenoid.
