“…The controller C PPF (s) has a positive low-frequency gain, which accords with positive position feedback (PPF). PPF is a damping method used in many structurally flexible systems [27]. Using negative imaginary theory, the stability of PPF control systems are readily guaranteed subject to simple criteria [28].…”

Abstract-In this brief, the transient performance of the signal transformation approach (STA) is considerably enhanced by initializing the state vector of the compensator to appropriate values. For triangular reference tracking, it is shown that the proposed method is identical to the impulsive state multiplication (ISM) approach. Through simulations and experiments, we also show that the proposed method can be equally applied to improve the STA for arbitrarily shaped desired signals, where ISM is not applicable. Tracking efficacy of the proposed method compared with that of an ordinary feedback loop with a similar noise rejection performance is also demonstrated.

“…As shown in Fig. 2, the PWPF modulator [5,[22][23][24] is composed of a Schmidt Trigger, a pre-filter, and a feedback loop. A Schmidt trigger is simply an on-off relay with a dead-zone and hysteresis.…”

“…Nevertheless, the problem is the determination of the width of the dead-band: if the width is too small there is a lot of useless and expensive chattering causing high fuel consumption; if the dead-band is too wide the control is less effective and there is a lot of residual motion. By adjusting pulse width and pulse frequency (PWPF) [22][23][24] to produce a pulse command sequence to the thruster valves, use of PWPF modulation control for large angle rotational maneuvers has been proposed by PWPF modulators are commonly employed in the spacecraft control system due to their advantages of reduced propellant consumption and near linear duty cycle.…”

This paper presents a dual-stage control system design method for the rotational maneuver and vibration stabilization of a spacecraft with flexible appendages. In this design approach, attitude control system and vibration suppression were designed separately using lower order model. The design of attitude controller was based on sliding mode control (SMC) theory leading to a discontinuous control law. This controller accomplishes asymptotic attitude maneuvering in the closed-loop system and is insensitive to the interaction of elastic modes and uncertainty in the system. The shaped command input controller based on component synthesis vibration suppression (CSVS) method is designed for reduction of flexible mode vibration, which only requires information about natural frequency and damping of the closed system. Additionally, to extend the CSVS method to the system with on-off actuators, pulse-width pulse-frequency (PWPF) modulation is employed to control the thruster firing and integrated with the CSVS method. Simulation results have been proven the potential of this technique to control flexible spacecraft.

“…PPF is also easy to implement. Song and Agrawal experimentally demonstrated that it is robust against a varying modal frequency [13]. Pang et al [14] used the selfsensing technique for active-mode damping in the dual-stage servo system.…”

This paper presents the self-sensing control of a microactuator for hard disk drives. The microactuator uses a PZT actuator pair installed on the suspension assembly. The self-sensing microactuator forms a combined sensing and actuation mechanism. Direct velocity feedback and positive position feedback are used in this paper. Our experimental results show that both strategies are effective in suppressing vibrational modes and successfully demonstrate the feasibility of using a self-sensing actuator on an HDD suspension assembly.
