ttm_pi_update - update proportional integral controller for a tip tilt mirror .

Calling Sequence

[ttm_pi_out,tt_command_out]=ttm_pi_update(ttm_pi_in,tt_residual,tt_command_in)

Parameters

• ttm_pi_in : the input proportional integral controller for the tip_tilt mirror.
• tt_residual : the Zernike mode residual for the tip-tilt mirror.
• tt_command_in : the input controlled command for the tip-tilt mirror.
• tt_command_out : the output controlled command for the tip-tilt mirror..
• ttm_pi_out : the output proportional integral controller for the tip_tilt mirror.

Description

update proportional integral controller for a tip tilt mirror.

Examples

	prop_gain = 1e-4;int_gain = 1e-3;
	pi=pi_controller(prop_gain,int_gain);
	ttm_pi=ttm_pi_controller(pi);
	tt_residuals=znk_mod(1);tt_command=znk_mod(1);
	[ttm_pi,tt_command]=ttm_pi_update(ttm_pi,tt_residuals,tt_command);
