Introduction

Contains PI controller with its related structures and functions.

Data Structures
struct	DCL_PI_SPS
	Defines DCL_PI shadow parameter set used for updating controller parameter. More...

struct	dcl_pi
	DCL_PI object for storing PI specific parameters. More...

Macros
#define	PI_SPS_DEFAULTS { 1.0f, 0.0f, 1.0f, -1.0f, 1.0f, -1.0f }
	Defines default values to initialize DCL_PI_SPS. More...

#define	PI_DEFAULTS
	Defines default values to initialize DCL_PI. More...

#define	PI_INT_DEFAULTS
	Macro for internal default values to initialize DCL_PI Example: DCL_PI pi_ctrl = { .Kp = 1.0f, .Ki = 0.0f, .Umax = 1.0f, .Umin = -1.0f, .Imax = 0.0f, .Imin = 0.0f, PI_INT_DEFAULTS };. More...

#define	DCL_initPI() &(DCL_PI)PI_DEFAULTS
	Initialize DCL_PI struct with default parameters Example: DCL_PI* pi_ctrl = DCL_initPI();. More...

#define	DCL_initPIasParam(kp, ki, umax, umin)
	Initialize DCL_PI struct with input controller parameters Example: DCL_PI* pi_ctrl = DCL_initPIasParam(1.0f,0.0f,1.0f,-1.0f); Note: input parameter needs to be in the same order as listed in PI_SPS struct. More...

#define	DCL_initPIasSPS(pi_ptr, sps_ptr)
	Initialize DCL_PI struct with sps parameters Example: DCL_PI_SPS pi_sps = { .Kp = , .Ki = , ...}; DCL_PI pi_ctrl; DCL_initPIasSPS(&pi_ctrl,&pi_sps);. More...

typedef _DCL_VOLATILE struct dcl_pi *	PI_Handle

Functions
_DCL_CODE_ACCESS void	DCL_resetPI (DCL_PI *pi)
	Resets PI internal storage data with interrupt protection. More...

_DCL_CODE_ACCESS void	DCL_forceUpdatePI (DCL_PI *pi)
	Loads PI tuning parameter from its SPS parameter without interrupt protection More...

_DCL_CODE_ACCESS _DCL_CODE_SECTION void	DCL_updatePINoCheck (DCL_PI *pi)
	Loads PI tuning parameter from its SPS parameter with interrupt protection. More...

_DCL_CODE_ACCESS _DCL_CODE_SECTION bool	DCL_updatePI (DCL_PI *pi)
	A conditional update based on the update flag. If the update status is set, the function will update PI parameter from its SPS parameter and clear the status flag on completion. Note: Use DCL_setUpdateStatus(pi) to set the update status. More...

_DCL_CODE_ACCESS void	DCL_loadSeriesPIasZPK (DCL_PI pi, DCL_ZPK3 zpk)
	Configures a series PI controller in "zero-pole-gain" form Note: Sampling period pi->css->T are used in the calculation. New settings take effect after DCL_updatePI(). Only z1 considered in DCL_ZPK3, other poles & zeros ignored. Zero frequency assumed to be in radians/sec. More...

_DCL_CODE_ACCESS void	DCL_loadParallelPIasZPK (DCL_PI pi, DCL_ZPK3 zpk)
	Configures a parallel PI controller in "zero-pole-gain" form Note: Sampling period pi->css->T are used in the calculation. New settings take effect after DCL_updatePI(). Zero frequency assumed to be in radians/sec. More...

_DCL_CODE_ACCESS _DCL_CODE_SECTION float32_t	DCL_runPISeries (DCL_PI *pi, float32_t rk, float32_t yk)
	Executes an inline series form PI controller. More...

_DCL_CODE_ACCESS _DCL_CODE_SECTION float32_t	DCL_runPIParallel (DCL_PI *pi, float32_t rk, float32_t yk)
	Executes a parallel form PI controller Implemented as inline C function. More...

_DCL_CODE_ACCESS _DCL_CODE_SECTION float32_t	DCL_runPIParallelEnhanced (DCL_PI *pi, float32_t rk, float32_t yk)
	Executes a parallel form PI controller with enhanced anti-windup logic incorporating an addintional integrator saturation clamp. More...
