Description

The Sliding Mode Controller block implements hysteresis-based sliding mode control (SMC).

Ports

Input

r — Plant reference

scalar

Plant system reference signal.

Data Types: single | double

y — Plant output

scalar

Plant system output signal.

Data Types: single | double

Output

u — Controller output

scalar

Control system output signal.

Data Types: single | double

Parameters

Hysteresis band — Hysteresis bandwidth

0.2 (default)

Total hysteresis bandwidth, distributed symmetrically about the set point.

Control action upper limit — Control signal upper limit, u_max

10 (default) | scalar greater than the value of the Control action lower limit parameter

Upper limit for the control output signal.

Control action lower limit — Control signal lower limit, u_min

-10 (default) | scalar

Lower limit for the control output signal.

Sample time (-1 for inherited) — Block sample time

-1 (default) | positive scalar

Time, in s, between consecutive block executions. During execution, the block produces outputs and, if appropriate, updates its internal state. For more information, see What Is Sample Time? and Specify Sample Time.

If this block is inside a triggered subsystem, inherit the sample time by setting this parameter to -1. If this block is in a continuous variable-step model, specify the sample time explicitly using a positive scalar.
