Feed-forward algorithms for time-optimal settling of hard disk drive servo systems 硬盘驱动器伺服系统时间最优沉降的前馈算法

The proposed method specifically minimizes the settling time of the servo positioning systems by applying an appropriate feedforward signal at seek-track hand off in the presence of bias disturbances. Two feedforward schemes have been investigated in the paper. They are the constant feedforward scheme and the exponential feedforward scheme. It is shown that while the former yields minimum settling time, the latter gives better robustness of the system performance when the estimation of the bias disturbance is subject to statistical errors. The proposed control schemes have been implemented on a test stand with a 3.5\" hard disk drive. Using the proposed scheme, seek time has been improved by as much as 38% for short seeks and 54% for long seeks. Both simulation and experimental results are shown. The proposed algorithms are simple and can be easily integrated with the existing disk drive servo control systems. The stability of the servo system been augmented will not be affected.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Point features are considered, and the feature matching is performed using a dynamic relaxation method. The proposed method examines the evidence in the local neighborhoods of a possible matching predicted and extracted feature pair and determines the validity of the current match. The advantage of the proposed method is that the match process is performed simultaneously for all possible matching features. The simultaneous process allows a set of possible matching pairs to compete against other sets of possible matching pairs without putting any restrictions on the order of which a match must be performed. The method may be especially attractive when the geometric relationships between features in an image are unclear. We demonstrate the effectiveness of the proposed method using several examples.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

On the other hand, the divergence of a light beam is much smaller than that of an ultrasonic beam, which allows for higher lateral resolution. In this paper, we show first the measuring technique and the system developed in this work.

An extension to the AFC, the modified AFC, is proposed to overcome some of the limitations of the AFC scheme. When designed to compensate for one runout frequency, the modified AFC can eliminate the intended harmonic without amplifying the adjacent harmonics. This eases the design of a controller to cancel multiple harmonics. Also, the modified AFC is more robust than the AFC since it improves the phase and gain margins. Simulation and laboratory implementation results are presented to show the performance improvements of the proposed modified AFC.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

This paper discusses a five-channel control signal transmission system so that it can simultaneously transmit five channels of parallel digital data at low frequencies. This new system is characterized by the realization of the BPFs used for data detection. Each frequency component is picked up from multifrequencies utilizing the DSP hardware in accordance with the algorithm used to realize a bandpass filter (BPF). The BPF output has a sharp cutoff which eliminates crosstalk among the other frequencies even though the frequency is in the range of 400 Hz to 600 Hz unlike the conventional BPF realized by operational amplifiers. When frequencies of 400 Hz and 600 Hz were applied to the BPF at the same time as and when the BPF had a bandpass characteristic at a center frequency of 500 Hz, the crosstalk was -40 dB or less. When an envelope of a stepwise input at a repetition rate of 1 Hz or less was applied, the delay time was 15 ms. Due to the excellent performance, multifrequency signals at low frequencies compress the bandwidth needed for transmission and eliminate the skewing of data transmission since the time delay is independent of the frequencies of the multifrequency signals.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.
