MUP r20150617

improvements/changes:

  • extended list of available "Robust MPC Approach":
  • added "Mao et Cao (2015)".
  • added "Mao et Huang (2015)".
  • added "Wan et Cao (2015)".
  • added "Wan et Huang (2015)".
  • added "Wan et Zhang (2015)".
  • updated YALMIP functions OPTIMIZE and VALUE, former SOLVESDP and DOUBLE, respectively.
  • extended features of CLI

fixed bugs:

  • fixed bug in sdp_ding and feas_ding, former release considered time-invariant uncertainties.
  • fixed bug in sdp_li and feas_li one-step-ahead policy of vertex assignment.

MUP v20150202

improvements/changes:

  • extended list of available "Robust MPC Approach":
  • added "Ding et al. (2007)".
  • added "Zhang et al. (2013)".
  • extended list of supported solvers:
  • added "MOSEK".

  • ensured backwards compatibility of plotted figures using rmpc_plot_r13b with MATLAB R2013b and sooner.
  • MUP toolbox is available for users of tbxmanager.

fixed bugs:

  • fixed bug in mup_rmpc_demo in addtitional control input saturation

known bugs and limitations:

  • RMPC method Ding et al. (2007) was implemented so that the time-invariant uncertainties were considered. Transformed for time-variant uncertainties in: MUP r20150616.
  • RMPC method Li et al. (2008) has a bug in the one-step-ahead policy of vertex assignment. Fixed in: MUP r20150616.
  • RMPC method Huang et al. (2011) has a bug in SDP constraints, there was missing the constraint related to upper bounds of Lyapunov functions. Fixed in: MUP r20150616.

  • fixed bug in the command-line-designed robust MPC using opt_cuzzola.m.

MUP v20141120

fixed bugs:

  • inserted missing m-file get_variat.m.

known bugs and limitations:

  • when designing the robust MPC directly in the command line by opt_cuzzola.m, then the robust MPC was not designed taking into account the robust invariant ellipsoid. When design the robust MPC using the rmpc_block in MATLAB/Simulink (i.e., using sdp_cuzzola.m), then the obtained results were correct. Fixed in: MUP v20141127.

  • initial version

known bugs and limitations:
