a comparator for comparing the measured value with the set point, calculating the difference or error between the two a control unit to calculate the output magnitude and direction to compensate the deviation from the desired value a output unit converting the output from the controller to physical...
of EP0704776 A comparator (1) forms the difference between a control parameter (x), measured at a control path (3) in a control loop, and a demand parameter, to determine a control value for the control path. The control loop is stimulated out of a stationary state. Instead of the ...

The AMMCLib User's Guide describes how the continuous-time PI controller can be discretized to obtain the difference equation suitable for implementation in the digital microcontroller. The equations GFLIB_ControllerPIp_Eq3 and GFLIB_ControllerPIp_Eq4 describe the calculation of the di...
value (measeured value) and Final value(desire value). If I run simulation with this configurations PI controller is tracking my desire value from zero and not from my measured valued like I want.First of all it is not the sum of desired and measured values, it should be the difference...
The parameterTscorresponds to the period of the interruption. The advantages/disadvantages of these different discretizations are well discussed in [1]. The Forward Euler will be used in this note, and the corresponding difference equation is given below. ...
at responding to errors away from the set point. The set point (SP) is the target value and process variable (PV) is the measured value that may deviate from the desired value. The error from the set point is the difference between theSPandPVand is defined ase(t)=SP−PVe(t)=SP-...
6. Conclusions We have proposed a new adaptive PI control method for temperature control of the testing platform of the air con- ditioner enthalpy difference method. The tuning methodol- ogy can estimate the parameters of the HVAC system accurately while the control system remains in the closed ...
This paper introduces a novel multi-stage FOPD(1 + PI) controller for DC motor speed control, optimized using the Pelican Optimization Algorithm (POA). Traditional PID controllers often fall short in handling the complex dynamics of DC motors, lead
A simulation illustration is presented to show the effectiveness and the performance of the designed FOPI controller compared with the optimized integer order PI controller and the IOPID controller designed following the same synthesis for the FOPI in this paper....
