This paper briefly introduces the H∞ loop shaping design procedure (LSDP) in the discrete-time case. Solution formulae are explicitly presented with the exposure of a relationship between the solutions to the three discrete-time, algebraic Riccati equations (DARE) required in the construction of an LSDP controller.
