Demanded actuator position, specified as a scalar or array.

Data Types: double

Output

expand all

Actual actuator position, returned as a scalar or array.

Data Types: double

Parameters

expand all

Natural frequency of the actuator, specified as a scalar double, in radians per second.

Programmatic Use

Block Parameter: wn_fin
Type: character vector
Values: scalar | double
Default: '1'

Damping ratio of the actuator, specified as a scalar double.

Programmatic Use

Block Parameter: z_fin
Type: character vector
Values: scalar | double
Default: '0.3'

Initial position of the actuator, specified as a scalar double. The units of initial position must be the same as the Ademand input.

Programmatic Use

Type: character vector
Values: scalar | double
Default: '0'

Initial velocity of the actuator, specified as a scalar double. The units of initial velocity must be the same as the Ademand input.
