This article reviews basic servo systems and development of the fault-tolerant feedback systems for servo systems. Controller receiver circuit design, proper PC-board receiver circuit layout, and the encoder's signal cable and termination are discussed. Additionally, various types of industrial feedback encoders are presented, along with the various types of faults that can develop in a servo f...

Asimple analytic method for transistor oscillator design has been developed. This technique defines explicit expressions for optimum values of feedback elements and load through bipolar transistor z-parameters. Such an approach is useful for practical optimization of a series feedback microwave bipolar oscillator. Microwave oscillator design in general represents a complex problem. Depending on...

In this Letter a feedback linearizing adaptive control system for the control of Chua’s circuits is presented. It is assumed that all the parameters of the system are unknown. Using a backstepping design procedure, an adaptive control system is designed which accomplishes trajectory control of the chosen node voltage by an independent voltage source. Simulation results are presented which show ...

The first adaptive feedback circuit capable of detecting resonant frequencies for a wide range of MEMS resonators is presented. The feedback system presented implements a hill-climbing algorithm that sweeps actuation frequencies, locking onto the resonance condition at maximum cantilever amplitude response without limitations on the frequency range. To demonstrate its adaptability, a circuit im...

This paper is concerned with transfer characteristics of a pneumatic micrometer system with a negative feedback transducer. The system has two negative feedback pathes. One of them is based on the transfer characteristics of the feedback transducer which is introduced to linealize the transfer characteristic of the system and the other is caused by repulsive pressure force between nozzle and it...
