Three methods of redesigning the sampling period to compensate known variations in the parameters of a discrete linear system are presented. These methods are based on the use of linearisations in the z-transform or in the time domains.

Inspec keywords: Z transforms; linear systems; transfer functions; compensation; discrete systems

Other keywords: time domains; sampling period; discrete linear system; digital controllers; z-transform; linearisations; dead-beat response

Subjects: Control system analysis and synthesis methods; Integral transforms; Discrete control systems
