Description: a gain-adjusted fuzzy PI/PD (GFPIPD) adaptive controller is proposed. The proposed controller first
constructs fuzzy rules for fuzzy PD/PI controller with the fixed weighting. Then the fuzzy rules, which self-learning their parameters for a desired condition, are learned through the accumulated GA. Finally, fuzzy gain-adjusted mechanism is further learned through the accumulated GA for the variations
of a measured system dynamics. The proposed GFPIPD controller is tested by the high order systems with time delay and variable system dynamics. The experimental results illustrate the performance of the proposed method.

Description: Focusing on the passive network, this paper analyzes
the discrete mathematical model and its control strategy of the
passive terminal of the VSC-HVDC system on the basis of the α-β
frame of axes. The method of the functioning-fuzzy-subset
inference is introduced into automatic regulation of the
proportional integral (PI) parameters. Based on the digital signal
processor (DSP), the fuzzy PI control method is adopted and the
VSC-HVDC experiment device is constructed. The experiment of
constant AC voltage control based on fuzzy adaptive PI controller
in transmitting power to passive network via VSC-HVDC system
is developed. Platform: |

Description: A hybrid fuzzy-PI controller for voltage source
converter based HVDC (VSC-HVDC) transmission system is
proposed in this paper. At first, the elementary model of VSCHVDC
is described. Then the fuzzy self-tuning control strategy is
proposed, in which direct current control strategy and dual
closed loop structure are designed in dq synchronous reference
frame. Independent control of the active and reactive power is
realized. Simulation results show that the designed control system
obtains satisfying performance, and the adjustments of power
flow could be achieved quicker than convention PI control. Platform: |

Description: A position control of a class of servomotors is addressed in this paper via a novel adaptive fuzzy PI sliding mode control. The premise and the consequence parts of the fuzzy rules are tuned with adaptive schemes. To attenuate chattering effectively, the discontinuous control is approximated by an adaptive PI control structure.Moreover, the bound of the discontinuous control term is assumed to be unknown, and an adaptive mechanism is used to estimate this bound. All adaptive laws are derived via Lyapunov synthesis method, thereby guaranteeing the closed-loop stability. The proposed approach has the added advantage that, for external disturbances, it only requires a bound to exist, without needing to know the magnitude of this bound. The proposed controller is applied to control a model of uncertain induction servomotor subject to significant disturbances and a model of DC servomotor with unknown parameters and uncertainty in load condition.

Description: This paper investigates the effect of membership functions in the fuzzy control of a chopper fed dc drive.
A Sugeno type fuzzy controller for closed loop control of dc drive fed by buck type dc-to-dc converter is
designed and considered for evaluation. The controller is used to change the duty cycle of the converter
and thereby, the voltage fed to the armature of the separately excited dc motor to regulate the speed.
Sugeno type fuzzy controller is selected for evaluation, as it is easy to implement in any embedded microcontroller
or DSP processor. The membership functions selected for evaluation are triangular, trapezoidal,
Gaussian, bell shaped and PI functions. Above evaluation is done considering both five and seven linguistic
sets for error and change in error. The results of the simulated performances are compared. The triangular
membership function shows better performance compared to other membership functions Platform: |

The compensation capabilities are not equivalent, with p-q control strategy unable to yield an adequate solution when source voltages are not ideal.
