“…On the other hand, the uncertainties and disturbance problems can be effectively addressed by adaptive control and learning control methodologies Krstic et al (1995); Xu and Yan (2006); Putra et al (2008). In future work, we will consider a systematic analysis and application of these approaches for engine control.…”

In this paper the control design methods for spark ignition engine models are discussed. Both single-input single-output (SISO) and multi-input multi-output (MIMO) systems are investigated for the design of an engine control system. A comprehensive comparative study for two classes of non-linear control methods, i.e. globally linearizing control (GLC) and sliding mode control, is given. The simulations results are presented to illustrate the capability and performance of the two kinds of controllers. The results show that the controller applying GLC can give accurate tracking for the engine model without uncertainty and disturbance; however, it fails to keep good tracking performance when uncertainty is considered. In contrast, the controller using the sliding mode is able to achieve the target, which shows that the engine system with the proposed sliding mode controller has good robustness to uncertainty and disturbance.

“…Several modifications to the PI operator have been proposed for rate-dependent hysteresis [7], [13], and [14] and creep compensation [4], [5], and [15]. Also, an adaptive rate-dependent controller, based on PI operators is proposed by [16] and [17]. The main drawback of the PI operator is the singularity problem which suffers due to negative gradients in the hysteretic path [14], [16].…”

Soft piezoelectric actuators are extensively used in micro-and nanopositioning applications. Traditional sensorless position control approaches use a hysteresis mapping between voltage and position in a voltage feedforward control scheme in order to compensate for hysteresis errors. However, several factors such as frequency, temperature, and aging influence this mapping. Recently, charge control for positioning is also attracting interest among researchers due to the linear relationship between position and charge. However, a sophisticated hardware design is required to minimize charge drift. In this study, a new sensorless position control technique is proposed which requires neither an accurate inverse mapping nor a sophisticated charge amplifier in order to compensate for hysteresis. A constitutive relationship is employed to infer position from charge measurement through current integration. To eliminate drift from the charge-based measurement, an observer is presented in this study which uses a second self-sensing position estimate that is based on the variation of effective piezoelectric capacitance with stroke. The proposed observer is tested as a position feedback sensor inside a simple integrating control loop and applied to step profiles of variable stroke and sinusoidal profiles of constant and mixed frequencies. The responses are compared with a laser interferometer and the maximum observer error between the laser and the observer is 0.89 μm (<3% of the maximum stroke) over a frequency range of 10 to 100 Hz.

“…E-mail: k-seki@nitech.ac.jp * Nagoya Institute of Technology Gokiso, Showa, Nagoya, Aichi 466-8555, Japan order to solve the problem, authors have already proposed the basic approach to suppress the bending vibration (8) . In the approach, the vibrations were suppressed by mounting a piezoelectric element (PZT) (9)- (11) on the mirror, where a multi-function of both sensor and actuator of the piezoelectric element was simultaneously applied to design the vibration suppression controller (called SSA: self-sensing actuation) (12)- (15) . However, since the suppression performance was insufficient for the mirror positioning time, the improvement of suppression performance have been required as a remaining work.…”

This paper presents a method for suppressing the bending vibration of galvano mirrors used in laser positioning systems. Fast and highly precise positioning of the mirror is vitally important for these systems. Thus, the flatness of the mirror should be maintained to ensure highly precise laser positioning. However, mechanical resonant vibrations of the mirror, which are excited by the moment force during positioning, lead to residual vibrations after positioning; these vibrations degrade the flatness of the mirror and the laser manufacturing accuracy. In this paper, therefore, a vibration suppression method is proposed in which a piezoelectric element is mounted on the mirror so as to utilize the multifunctionality of the piezoelectric element by applying it as both actuator and sensor in the vibration suppression controller design. The applicability of the proposed approach to industrial galvano scanners has been verified by performing experiments with a prototype.
