The design of optimal dead-beat controllers for first-order plants is considered. The simple nature of these plants leads to ripple-free step response, a property that is highly desirable. The minimum energy and minimum effort control problems are formulated and solved with an analytical and generalized approach. Analytical expressions for the digital controller pulse transfer functions along with the resulting control sequences are derived. Generalized curves for the maximum control signals… Expand

TLDR
The design of digital controllers for minimum-energy ripple-free dead-beat control of type-I second-order plants is considered and it is readily seen that a linear increment in the overall system order results in a proportional increase in the settling-time and an exponential decrease in the energy of the control signal needed to attain the desirable response, but the maximum control signal, as well.
