Description: 在分析无刷直流电机（BLDC）数学模型的基础上，提出了一种无刷直流电机控制系统仿
真建模的新方法。在Matlab/Simulink环境下，把独立的功能模块和S函数相结合，构建了无刷直流
电机系统的仿真模型。系统采用双闭环控制：速度环采用离散PID控制，根据滞环电流跟踪型PWM
逆变器原理实现电流控制。仿真和试验结果与理论分析一致，验证了该方法的合理性和有效性。
此方法也适用于验证其他控制算法的合理性，为实际电机控制系统的设计和调试提供了新的思路。
-Based on the mathematical model of the Brushless DC motor(BLDC),a novel method for modeling and
simulation of BLDC control system was proposed.In Matlab/Simulink,by the combination of the isolated functional blocks
and S-functions,the model of BLDC could be established.In the double loop of control system,a discrete PID controller was
adopted in the speed loop and a current controller was completed in the current loop on the principle of hysteresis current
track PWM inverter.The reasonability and validity were testified by the coincidence of the simulation and experimentation
results and theory analysis.This novel method is also suitable for verifying the reasonability of other control algorithms and
offers a new thinking for designing and debugging actual motors.

Description: As traditional control schemes, open-loop Hysteresis and closed-loop pulse-width-
modulation (PWM) have been used for the switched reluctance motor (SRM) current controller. The Hysteresis controller induces large unpleasant audible noises because it needs to vary the switching frequency to maintain constant Hysteresis current band. In contract, the PWM controller is very quiet but difficult to design proper gains and control bandwidth due to the nonlinear nature of the SRM. In this thesis, the ac small signal modeling technique is proposed for linearization of the SRM model such that a
conventional PI controller can be designed accordingly for the PWM current controller. Platform: |

Description: In this paper, a comparison is made between different
implementations of the three-level torque comparator
for a Direct Torque Control (DTC) based induction motor
drive. The DTC scheme controls stator flux and torque by
means of hysteresis comparators, respectively a two-level control
structure for the stator flux and a three-level comparator for
the electromagnetic torque. The standard three-level hysteresis
controller has a DC offset torque error. In this paper, an
additive implementation is investigated in order to remove this
DC offset error. The operational principles of the different
implementations are compared based on continuous and discrete
simulation results, which demonstrate the additional advantages
of the additive structure in a discrete implementation of the
control scheme. Platform: |

Description: This paper proposes an open switch faults detection and localization algorithm for shunt three
phase active filter topology. It mainly details converter configuration and examines a simple and
reliable optimised fault diagnosis method. The con verter topology is based on classical three-leg
active power filter topology. A ne w fault diagnosis method is proposed, based on classical
currents measurements. It includes combinatory logic to analyse and validate error signals. A
Hysteresis Control is applied before and after fault detection, which avoids any controller
reconfiguration. Simulation results obtained with Matlab/Simulink/Plecs tools prove the
effectiveness of this method. -This paper proposes an open switch faults detection and localization algorithm for shunt three

Description: This paper describes a torque ripple reduction technique with constant switching frequency for direct
torque control (DTC) of an induction motor (IM). This method enables a minimum torque ripple control. In order to obtain a constant switching frequency and hence a torque ripple reduction, we propose a control technique for IM. It consists of controlling directly the electromagnetic torque by using a modulated hysteresis controller. Platform: |

Description: Induction motor drive based on direct torque control (DTC) allows high dynamic performance to be obtained with very simple hysteresis control scheme.
Once the DTC is fully and deeply described, its main drawbacks are introduced. One of the goals of the present paper is to overcome one of the worst disadvantage of DTC, which is the existence of a considerable ripple in its torque response. The previously explained DTC limitations involve plenty of nonlinear functions. Therefore, artificial intelligence is suggested to overcome the DTC limitations. Hence, a Fuzzy logic DTC controller, which is based on the classical DTC but includes a fuzzy logic controller, is fully described. We carry out a detailed comparison study between conventional direct torque control
(CDTC) and direct torque fuzzy control (DTFC).
