Controllability vs reachability

August undefined, 2024

In systems with limited control authority, it is often no longer possible to move any initial state to any final state inside the controllable subspace. This phenomenon is caused by constraints on the input that could be inherent to the system (e.g. due to saturating actuator) or imposed on the system for other reasons (e.g. due to safety-related concerns). The controllability of systems with input and state constraints is studied in the context of reachability and viability theory. http://control.asu.edu/Classes/MMAE543/543Lecture11.pdf

22.2: The Reachability Problem - Engineering LibreTexts

WebAs nouns the difference between reachability and controllability. is that reachability is the condition of being reachable while controllability is the quality of being controllable; controllableness. WebA dynamic system is said to be controllable if it is possible to apply control signals that drive the system to any state within a finite amount of time. This characteristic is also called reachability. ctrb computes a controllability matrix from state matrices or from a state-space model. You can use this matrix to determine controllability uncle ben wild rice chicken casserole

From (22.2) we see that this requires solving Web• general state transfer reduces to reachability problem • if system is controllable any state transfer can be achieved in ≤ n steps • important special case: driving state to zero (sometimes called regulating or controlling state) Controllability and state transfer 18–8 uncle berchWebA state x_0 is called controllable if there exists an input that transfers the state from x_0 to the zero state in some finite time T. So in other words, reachability is going from the zero state to some other state while controllability is going from some state to the zero state. The authors also use the term controllable-from-the-origin for ... uncle ben with great power

"Webrefer to this problem as the reachability problem. If for x0 = 0, there exists an input u which solves the reachability problem, we then say that the state x is reachable from 0 at time t. We refer to such an input u as the control which transfers the state from the origin to x at time t. Denote the set of states reachable from 0 by R0. " - Controllability vs reachability
