چکیده
This paper presents an optimization method that aims to mitigate disturbances in the radial-feed system of ring-pendulum double-sided polisher (RDP) during processing. We built a model RDP and developed single-tube robust predictive control enhance disturbance rejection capability system. To constrain states inside terminal constraint set further system’s robustness, we added ε-approximation approach set. Finally, effectiveness proposed for was verified through simulations experiments. These findings demonstrate potential improving performance practical applications. The polish processing results demonstrated substantial improvement accuracy surface shape measurements obtained by applying STRMPC method. Compared MPC method, PV value decreased from 1.49 λ 0.99 PV, indicating convergence rate approximately 9.78%. Additionally, RMS 0.257 0.163 RMS, demonstrating remarkable 35.6% enhancement rate.

Design Optimization and Construction of Double-Sided Linear Induction Motor
Linear induction motors have single and double-sided structures which are used in special applications, according to their advantages and disadvantages. Due to advantages such as lack of normal forces in double-sided type, these motors are more controllable and popular than the single-sided type, especially for transportation applications. In literature, single-sided linear induction motors ha...
متن کاملMelnikov’s Method Applied to the Double Pendulum
Melnikov’s method is applied to the planar double pendulum proving it to be a chaotic system. The parameter space of the double pendulum is discussed, and the integrable cases are identified. In the neighborhood of the integrable case of two uncoupled pendulums Melnikov’s integral is evaluated using residue calculus. In the two limiting cases of one pendulum becoming a rotator or an oscillator,...
متن کاملAchievement of High Flatness of Large Diameter Silicon Wafer in Double-sided Polishing -optimization of Polishing Conditions Based on Kinematical Analysis-
INTRODUCTION Semiconductor devices require silicon (Si) wafers as the substrates to be manufactured with very high flatness for miniaturizing the design rule. On the other hand, the size of wafer is increasing for raising the number of device chips per a wafer for reduction of the process cost. Recently, 300 mm diameter wafers are mainly manufactured, and the feasibility study for 450 mm diamet...
متن کاملDouble Pendulum
The double pendulum is a classic dynamical system, capable of chaotic behavior in a four-dimensional phase space. The driven case introduces even more peculiar behaviors and opens the possibility for stable folded modes. In this paper, we explore the double pendulum in both driven and undriven cases through experimental observation and simulations, focusing on time-to-flip as a major measure of...
متن کاملA TWO-STAGE SIMP-ACO METHOD FOR RELIABILITY-BASED TOPOLOGY OPTIMIZATION OF DOUBLE LAYER GRIDS
For reliability-based topology optimization (RBTO) of double layer grids, a two-stage optimization method is presented by applying “Solid Isotropic Material with Penalization” and “Ant Colony Optimization” (SIMP-ACO method). To achieve this aim, first, the structural stiffness is maximized using SIMP. Then, the characteristics of the obtained topology are used to enhance ACO through six modific...
