ControlDesign

 Calling Sequence ControlDesign[command](arguments) command(arguments)

Description

 • The ControlDesign package is a collection of procedures for creating and designing control systems.
 • This package makes use of the tools present in the DynamicSystems package.
 • The Digits environment variable can be increased to accommodate designs which require greater numerical precision. See Digits for more details on how to change the number of digits that Maple uses when handling software floating-point numbers.
 Note: The symbols used for the continuous time variable, complex frequency variable, discrete frequency variable, discrete time variable, input variable, output variable, and state variable must be unassigned or changed before using the DynamicSystems package. See SystemOptions for more details.
