Introduction For linear time-invariant (LTI) setpoint control systems, input shaping is a powerful technique to reduce residual vibrations in those systems as shown in [1]. The targeting trajectory can be optimized (e.g. minimize targeting time or energy consumption) through convex optimization techniques. A broad overview of real-time or nearly real-time applications has been given in [2]. Inp...

The flexibility of long reach manipulators presents a difficult control problem when accurate endpoint position is required. To maintain a desired tip trajectory, the residual vibration inherent to flexible systems must be eliminated. Unfortunately, vibration suppression is often difficult to achieve in systems whose parameters are a function of configuration. This paper discusses a modified co...

This paper proposes a design method of a damping path for a cylindrical liquid container transferred with a wheeled mobile robot. The damping path is constructed from the acceleration using the principle of an input shaping method. Although a positional error is occurred by using the input shaping method, it is easy to correct the error with the proposed method. The proposed design method can b...

This paper presents an investigation into development of feed-forward and feedback control strategies for active vibration suppression and attitude control of flexible spacecrafts. The feed-forward loop consists of a computed-torque scheme and a command shaping technique based on component synthesis vibration suppression (CSVS) method which was developed based on linear systems theory. For rela...

this paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. in this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. the robust controller is designed on the basis of fractional lyapunov stability theory. furthermore, the effects of model uncertainti...
