Discrete-time Frequency-shaped Sliding Mode Control for Audio-vibration Rejection in Hard Disk Drives ?
In this paper, a discrete-time frequency-shaped sliding mode control (FSSMC) is proposed for audio-vibration rejection in Hard Disk Drives (HDDs). Such vibrations cause significant degradation of the servo performance and have become a major concern in the HDD industry. The proposed FSSMC involves the frequency-shaped sliding surface design based on peak filters, aiming to provide frequency dep...
متن کاملA New Method for Time-Delay Compensation in Control Systems
In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
متن کاملNeural Network Based Sliding Mode Control for Uncertain Discrete-Time Nonlinear Systems with Time-Varying Delay
The present paper discusses the stability analysis of discrete-time uncertain nonlinear systems with time-varying delay, uncertainties related to parametric uncertainty and unknown nonlinearity. The time-varying delay considered has minimum and maximum bounds. The novelty of Chebyshev Neural Network (CNN) is that it requires much less computation time as compared to multi layer neural network (...
متن کاملSecond Order Sliding Mode Control With Finite Time Convergence
In this paper, a new smooth second order sliding mode control is proposed. This algorithm is a modified form of Super Twisting algorithm. The Super Twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular Lyapunov function. The Proposed algorithm which is able to control nonlinear systems with matched structured u...
متن کاملSliding Mode Control for a Plant with a Time Delay
In this study, we propose an advanced sliding mode control (SMC) technique for plants with time delays. In control engineering, the presence of time delays in a control system may cause it to become unstable. Furthermore, SMC cannot control systems having time delays. To solve this problem, we introduce a simple plant predictor to the SMC method. Therefore, our proposed method is designed easil...
