“…The double integrator is a canonical example, which has often been used to illustrate the application of novel control techniques (Vieira et al 2011;Gustafsson 1996;Sun et al 2017). The states x 1 , x 2 and the control input u can be interpreted as position, velocity and acceleration variables for either translational or rotational motion (Bernstein 2009).…”

“…In this context, a mixed-integer predictive control approach was proposed in (Vieira 2013), with preliminary results reported in (Vieira et al 2011). The proposed formulation employed normalized control actions with integer values −1, 0, +1, where 0 corresponds to closed thrusters, and −1, +1 correspond to thrusters opened in the clockwise or counterclockwise direction.…”

This paper is concerned with the control of linear systems with switched actuators subject to lower bounds on dwell times. The problem addressed herein consists of driving the system state to a desired periodic trajectory through suitable perturbations in the switching times. For this purpose, a linearization procedure is derived to describe the relationship between the switchingtime perturbations and the resulting state trajectory. This procedure allows the constrained predictive control problem to be cast in the form of a convex quadratic program, which is a key contribution of the present work. Simulation examples with single-input and two-input models are presented for illustration. In all cases, the system state is driven to the desired trajectory with satisfaction of the dwell-time constraints on the switched input signal.

“…A wide variety of control techniques have been proposed in the literature for ACS design based on on/off actuators, including bang-bang control [8], linear quadratic regulators (LQR) with pulsewidth pulse-frequency modulators (PWPF) [9,10], mixed-integer linear programming (MILP) control allocation [11], and model predictive control (MPC) [12,13]. While many of these techniques explicitly account for minimum firing duration constraints, they do not address the problem of minimizing the overall number of thruster firings, which has a key impact on the lifetime of the thrusters and hence of the mission itself.…”

Recent technological advances in the development of electric microthrusters pave the way to the successful diffusion of all-electric spacecraft. Since pointing accuracy is a key requirement for space platforms, suitable control systems accounting for the peculiarity of electric on/off actuators have to be devised. In this paper, an attitude control system (ACS) for spacecraft equipped with cold gas and electrothermal xenon microthrusters is presented. The number of thruster firings, which has a key impact on the thruster lifetime, is explicitly taken into account in the control design phase. By adopting a model predictive control (MPC) approach, a cost functional including both fuel consumption and number of firing cycles is minimized at each time step, within a receding horizon scheme. The effectiveness of the proposed ACS is validated on a sample GEO mission and its performance is compared with different control laws involving on/off actuators.

Abstract-This paper studies an important aspect of attitude control for a launcher's upper stage: the minimum impulse bit (MIB), that is, the minimum torque that can be exerted by the thrusters. We model this effect using principles of hybrid systems theory and we design a hybrid model predictive control scheme for the attitude control of a launcher during its long coasting period, aiming at minimizing the number of thrusters' actuations. We apply the proposed methodology to a nonlinear model of a typical upper stage with multi-payload capability.
