One is the weighted switching lifted digitally redesigned tracker, the other is the output-reference tracking digitally redesigned tracker. The former is aimed to the lifted performance of the weighted switching, and the latter is aimed to remove the influence of external loads. For various reasons, the energy delivered from plant to plant in cascaded system is bounded. This can be described by a bound on the internal state amplitude of the cascaded system. If this limitation is omitted in the control design, unexpected phenomena can affect the closed-looped system, and the closed-loop system can become unstable in the worst case. The effect of this constraint can be abated by using the weighted switching strategy that it makes system out of saturation region as soon as possible. The lifted technique and the output-reference tracking scheme are used to increase the performance of the digital redesigned controller and to remove the influence of external loads, respectively. The main realizations of controllers are based on above-mentioned methodologies and to associate with the digital implementation of microprocessors and digital signal processing chips.
