Servo-Amplifier Design

Harmonic Drive Motor Load Servo Amplifier

Despite widespread industrial application of harmonic drives, mathematical representation of their dynamics has not been fully addressed. In this theoretical/experimental study of harmonic drive systems a systematic way to capture and rationalize the dynamics of the system is proposed. Simple and accurate models for compliance, hysteresis, and friction are given and the model parameters are est...

Design Servo System Type and Positioning of Pole Observer Full Rank a Piezoelectric Servo Valve without Integrator

In this paper, the method of modern control approach for the design of controller and observer is used. Other functions such as neural controllers - or fuzzy sliding mode control can be found in this work and the results are compared. First, a dynamic model of the servo valve is intended for the governing equations in state-space form expression are obtained. Due to the system integrator is exp...

Design, Analysis and Simulation of a Linear Phase Distributed Amplifier

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....

Multiple Multi-Objective Servo Design - Evolutionary Approach

Design of control systems is characterised by many targets, therefore the methods enabling optimisation of several objectives have received more and more attention over the past years. When dealing with multi-objective optimisation problems the notion of the scalar function optimality was extended. The most common approach was originally proposed in 19th century by Edgeworth and later generalis...
