    This article presents a quantitative analysis of error tracking among various model-based feed-forward remote controls such as z-magnitude error tracking control (ZMETC) , non-minimum -Phase-Zero-Ignore-Traffic-Monitoring-Control(NMPZITC) in various control architectures with several degrees of freedom (2-DOF). The analysis shows that 1) even when there is no product uncertainty, additional forecasting conditions are almost always required for additional compensation, such as speed, acceleration, jerk and forecast; 2) A non-causal implementation that goes beyond the causal link of inclusion of model-based prediction strategies leads to further tracking errors and requires additional free compensation. Based on the analysis, a formula for the algorithm for correcting conditions in case of too large a lead is proposed. The simulation and enjoyment of the ultra-precise motion system also confirms the analysis theory and the proposed algorithm.

  • The evolution of nanotechnology will include precise tracking of periodic mappings to perform repetitive business or scientific tasks. While repeating sustain is an intuitive choice for accurate periodic signal tracking, some integer must match the period with digital control network signals or performance will be severely degraded. So, on paper, good repetitive mastering based on a fractional delay filter (FDFRC) is designed to achieve consistent signal tracking with arbitrary periods. In accordance with the principle of the internal model, a true fractional delay filter is often designed with a spectrum selection property using a Farrow structure to correct integer/non-integer delays. It also defines and analyzes the stability of the FDFRC to make it easier to implement a domain controller. Proposed FDFRC approvalGives a simple, easy, simple and practical parameter, in which only the i parameter can be adjusted for unusual integer/non-integer delays. Comparative experiments with different frequencies of triangular waves for the z-axis and Lissajous xy-scan in the plane on a piezoelectric nanopositional junction are being carried out to further test how the proposed controller significantly improves tracking capabilities. /p>

    On paper, this is again a proactive approach by measuring the iterative learning control (ILC) signal. Implementation of precision motion systems is proposed. The idea is that since the ILC may want to achieve excellent tracking performance, the ILC reception contains useful information about the tracking dynamics and therefore can be widely used to efficiently tune the predictive controller based on the model. Thus, ILC altitude performance can be obtained while ILC sensitivity to reference path change can be discarded.on the. In the proposed algorithm, acceleration, cooling, and instantaneous advance are tuned by passing the ILC signal through the least number of areas first; then the remaining tracking error is compensated by the predictive controller based on the redundant model, the structure of my controller is determined by the Monte Carlo method, and the parameters of some controllers are also adjusted, becoming the least squares ILC signal. And modeling experiments with the exact range of motion of systems confirm both the theoretical test and the proposed algorithm.

    On paper, all of this Variable Gain Phase Feedback (PBVGC) processing is used for the Precision Systems Upgrades exploit. movement. Undoubtedly, an analysis of the possibilities of the control strategy is presented, a stability analysis is given, as well as the Lyapunov quadratic joint function method, and a data-driven tuning approach for design variables based on a finite difference design is proposed. And the expertThe Precision Motion System Simulation Tests both the phase variable gain feedback control algorithm and the proposed adaptation approach.

    This article describes a flexible predictive controller for creating a path with stable and unstable zeros that vary to the correct exit time. The dynamics of this special control scheme, consisting of a system and a feedback controller, react in unknown or slowly varying ways due to changes in system parameters. The control scheme proposed prior to this article, the feed-forward controller, is universal, while the feedback controller is fixed on the assumption that the established loop system remains almost temporarily stable. With multiple samples of future reference inputs available, the preview action of the universal predictive controller compensates for the phase shift generated by the feedback dynamics.tight coupling, and also provides zero complex phase error for performance control (i.e., the output platform will be in phase). with any desired sinusoid) asymptotically. Numeric

    Introduced predictive control criterion for tracking desired alerts over time. The lead clears all poles in the closed loop and also clears erasable zeros in the closed loop. For non-cancelled zeros, which typically include zeros outside of the unit circle image, the feedforward controller cancels the process shift they caused. Trace compensation ensures that the frequency response between the desired output signal and the actual output signal exhibits zero phase shift with respect to all frequencies. The program is especially useful for general motion control tasks, including robotic arms and positioning tables. A typical motion control task is used to demonstrate the specific performance of a proposed controller.but ahead of schedule.
