Feed-forward temperature compensation for Hall effect devices
Journal of Physics E: Scientific Instruments, 1982The temperature dependent zero-field offset voltage of a Hall effect device (HED) is normally removed by a separate compensating network. Utilising the HED itself as a temperature transducer, however, results in a more accurate compensation scheme. A DC-10 kHz fluxmeter incorporating this approach is described which displays only +or-1.0% variation in ...

Advanced self-commissioning and feed-forward compensation of inverter non-linearities
2015 IEEE International Conference on Industrial Technology (ICIT), 2015Accurate compensation of inverter non-linearities is highly desirable especially in high performance drives where a perfect correspondence between reference voltages and real output voltages is required. In this paper a self-commissioning procedure able to determine each contribute to the overall output voltage distortion and save it to a Look-Up Table

11 GHz UGBW Op-amp with feed-forward compensation technique
2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011A high speed pseudo differential three stage operational amplifier has been implemented using a feed-forward compensation technique in a standard 0.13 µm CMOS technology. The three stage inverter based op-amp with feed-forward compensation achieves 11 GHz of unity gain bandwidth for a nominal power consumption 18 mW, and exhibits 39 dB of DC gain with ...

General feed-forward input filter compensation method
1983 IEEE Power Electronics Specialists Conference, 1983For several reasons a switching regulator is always preceeded by an input filter, and this impairs all essential parameters of the regulator. The extended injected- absorbed current analysis method culminates in a truly general switching cell model, which, embedded in a closed-loop structure, results in a general model of a switching regulator.

Feed-forward Compensation of load and parameter variations of electric drive
2008 13th International Power Electronics and Motion Control Conference, 2008The paper presents a method to compensate effects caused by slow varying loads and plant parameters drift as well as by detuned controller using a simple yet robust algorithm in voltage controlled electric drives. In case of known variations an analytical expression of pre-computed feed-forward compensation voltage is derived, while in presence of ...

Adaptive PI control with feed-forward compensator for a weigh feeder
2009 International Conference on Networking, Sensing and Control, 2009This paper proposes a new method for designing a weigh feeder controller. The dynamic characteristics of a weigh feeder are time-varying and its high frequency vibration modes are not easily identified. Hence, the precise model of a weigh feeder cannot be obtained.

Frequency domain based feed forward tuning for friction compensation
2010In high precision motion control, performance is often limited by the presence of nonlinearities. In this study, the presence of nonlinear influences in a high precision transmission electron microscope stage is investigated using broadband multisine signals.

Dead−time and feed−forward disturbance compensation for congestion control in data networks
International Journal of Systems Science, 2003Two major features characterize the congestion control problem in modern data networks: (1) propagation delays, which may have an adverse impact on the stability of closed loop congestion control algorithms, and (2) time−varying available bandwidth. To deal efficiently with these issues, it is proposed to design the controller by employing both dead ...
