Synthesis of modulated-demodulated control systems

چکیده
We propose systematic design methods for realization of a given LTI compensator with complex poles using a modulated–demodulated control framework. Applicability of the proposed realization methods is established through simulations performed on an undamped resonant plant compensated by a low gain controller to obtain better noise rejection performance. It is demonstrated how a modulated–demodulated structure may reduce the sampling rate in a hybrid control system. In addition, superior robust performance is achieved against variations in baseband parameters using direct reference injection into themodulated–demodulated control systems compared to the indirect injection approach. © 2014 Elsevier Ltd.

Modulated–demodulated control: Q control of an AFM microcantilever
We outline the application of modulated–demodulated control to the quality (Q) factor control of an atomic force microscope microcantilever. We review the modulated–demodulated control technique, emphasize its linear time invariant nature and develop state space representations of the controller for design and analysis. The modulated–demodulated controller can be configured as both positive pos...
متن کاملPosition Control of a Pulse Width Modulated Pneumatic Systems: an Experimental Comparison
In this study, a new adaptive controller is proposed for position control of pneumatic systems. Difficulties associated with the mathematical model of the system in addition to the instability caused by Pulse Width Modulation (PWM) in the learning-based controllers using gradient descent, motivate the development of a new approach for PWM pneumatics. In this study, two modified Feedback Error L...

A 3-axis 12-bit CAN-compatible MEMS inertial sensor cluster for vehicle dynamics control is presented. The sensor cluster can measure the x/y-axis accelerations and z-axis rotation. The MEMS sensing elements are fabricated using the sacrificial bulk micromachining (SBM) process. The sensor interface circuit is fabricated using a standard 0.18-μm CMOS process. The input capacitive amplifier adop...
متن کاملISAR Imaging Based on the Wideband Hyperbolic Frequency-Modulation Waveform
The hyperbolic frequency-modulated (HFM) waveform has an inherent Doppler-invariant property. It is more conducive than the conventional linear frequency-modulated (LFM) waveform to high speed moving target imaging. In order to apply the HFM waveform to existing inverse synthetic aperture radar (ISAR) imaging systems, a new pulse compression algorithm is proposed. First, the received HFM echoes...
متن کاملTwo-dimensional differential demodulation for OFDM
In this paper, the possibility of combining differential demodulators in time direction and frequency direction for orthogonal frequency-division multiplexing (OFDM) frames is investigated. The proposed algorithm uses not only the direction in which the information is modulated, but also joins it with other symbols in time or frequency direction of the OFDM frame, resulting in an additional sec...
