Optimal switching between controlled subsystems with free mode sequence
نویسندگان
چکیده
The problem of optimal switching and control of nonlinear switching systems with controlled subsystems is investigated in this study where the mode sequence and the switching times between the modes are unspecified. An approximate dynamic programming based method is developed which provides a feedback solution for unspecified initial conditions and different final times. The convergence of the proposed algorithm is proved. Versatility of the method and its performance are illustrated through different numerical examples.

Robust Optimal Speed Tracking Control of a Current Sensorless Synchronous Reluctance Motor Drive using a New Sliding Mode Controller
This paper describes the robust optimal incremental motion control of a current sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...
متن کاملOptimal Switching Instants of Linear Switched Systems Based on Meta-heuristic Approaches
In this paper, optimal control problems for switched systems are studied. In particular, we focus on such problems given a prespecified sequence of active subsystems and propose two approaches based on meta-heuristics to find the optimal switching instants. The first one is based on the Genetic Algorithm (GA) and the second on the Particle Swarm Optimization (PSO) algorithm. The objective is to...
