Understanding how to tailor quantum dynamics to achieve a desired evolution\nis a crucial problem in almost all quantum technologies. We present a very\ngeneral method for designing high-efficiency control sequences that are always\nfully compatible with experimental constraints on available interactions and\ntheir tunability. Our approach reduces in the end to finding control fields by\nsolving a set of time-independent linear equations. We illustrate our method by\napplying it to a number of physically-relevant problems: the strong-driving\nlimit of a two-level system, fast squeezing in a parametrically driven cavity,\nthe leakage problem in transmon qubit gates, and the acceleration of SNAP gates\nin a qubit-cavity system.\n
