how to use hysteresis current controller

hi i need some information on how to use hysteresis current controller, is there any block or any thing related in matlab simulink?

Answer 1

[Fangjun Jiang]

Not sure what you mean by "hysteresis current controller". Are you looking for some blocks to deal with hysteresis? Check the Relay block, Backlash block, Dead Zone block, or Coulomb & Viscous Friction block in Simulink library->Discontinuities

if you want to control cureent of inverter , you can use Relay block as hysteresis current controller to PWM since yhe output of relay is only 1 or 0 to produce a clock in order to control your inverter.

Can you help me . I want use hysteresis output of relay is 4 level ( 2 or 1 or 0 or -1) for controler with error
