Abstract :
The locus of a perturbed relay system (LPRS) method is being extended to nonlinear plant case in the paper. The nonlinear plant extension of this method is based on the main property and some other features of LPRS. A numeric integration approach is considered. An extended definition of LPRS for its open-loop output spectrum based computing is given. An example of design of the relay pneumatic servo system is considered in the paper
