Dead Zone Inverse Compensation

In order to compensate a dead zone in an actuator, dead zone inverse method can be used. May I know how do you implement the dead zone inverse model in Simulink?

Hello Dongmiao,

There is no block that can perform the inverse dead-zone functionality as of now. However, 'finverse' function can be used to block to acheive this functionality.

Also the inputs and the outputs considering dead-zone could be logged for a particular actuator. These inputs and outputs can then be used as table data and breakpoints respectively in a 1-D lookup table to achieve the inverse mapping needed for dead-zone compensation.
