Abstract : The research is concerned with digital control of dynamic systems and with the design of programable digital controllers (PDC's) which are linked to a coordinating central computer. A specific PDC form is suggested which, with large scale integrated circuits (LSI circuits) and modular design, should prove feasible and useful for certain naval systems. Specific logic designs are suggested for some units of this PDC, but a detailed logic design to the gate level, and most of the timing logic, are left for future research and development. Multi-mode sampled-data control laws are derived for obtaining insensitive and nearly time-optimal control of low-order dynamic systems. In addition to linear small-signal regions, nonlinear small-control signal regions are introduced to obtain smooth transition between what would otherwise be bang-bang modes of control. (Author)
